Compressed Data Packet (Tag 8)
The Compressed Data packet contains compressed data. Typically, this packet is found as the contents of an encrypted packet, or following a Signature or One-Pass Signature packet, and contains literal data packets.
The body of this packet consists of:
A Compressed Data Packet's body contains an block that compresses some set of packets. See section "Packet Composition" for details on how messages are formed.
ZIP-compressed packets are compressed with raw RFC 1951 DEFLATE blocks. Note that PGP V2.6 uses 13 bits of compression. If an implementation uses more bits of compression, PGP V2.6 cannot decompress it.
ZLIB-compressed packets are compressed with RFC 1950 ZLIB-style blocks.
typedef struct pgpPktEdata_s pgpPktEdata |
5.7.
Symmetrically Encrypted Data Packet (Tag 9)
The Symmetrically Encrypted Data packet contains data encrypted with a symmetric-key algorithm. When it has been decrypted, it will typically contain other packets (often literal data packets or compressed data packets).
The body of this packet consists of:
The symmetric cipher used may be specified in an Public-Key or Symmetric-Key Encrypted Session Key packet that precedes the Symmetrically Encrypted Data Packet. In that case, the cipher algorithm octet is prefixed to the session key before it is encrypted. If no packets of these types precede the encrypted data, the IDEA algorithm is used with the session key calculated as the MD5 hash of the passphrase.
The data is encrypted in CFB mode, with a CFB shift size equal to the cipher's block size. The Initial Vector (IV) is specified as all zeros. Instead of using an IV, OpenPGP prefixes a 10-octet string to the data before it is encrypted. The first eight octets are random, and the 9th and 10th octets are copies of the 7th and 8th octets, respectively. After encrypting the first 10 octets, the CFB state is resynchronized if the cipher block size is 8 octets or less. The last 8 octets of ciphertext are passed through the cipher and the block boundary is reset.
The repetition of 16 bits in the 80 bits of random data prefixed to the message allows the receiver to immediately check whether the session key is incorrect.
typedef union pgpPktKey_u pgpPktKey |
5.5.3.
Secret Key Packet Formats
The Secret Key and Secret Subkey packets contain all the data of the Public Key and Public Subkey packets, with additional algorithm- specific secret key data appended, in encrypted form.
The packet contains:
Algorithm Specific Fields for RSA secret keys:
Algorithm Specific Fields for DSA secret keys:
Algorithm Specific Fields for Elgamal secret keys:
Secret MPI values can be encrypted using a passphrase. If a string- to-key specifier is given, that describes the algorithm for converting the passphrase to a key, else a simple MD5 hash of the passphrase is used. Implementations SHOULD use a string-to-key specifier; the simple hash is for backward compatibility. The cipher for encrypting the MPIs is specified in the secret key packet.
Encryption/decryption of the secret data is done in CFB mode using the key created from the passphrase and the Initial Vector from the packet. A different mode is used with V3 keys (which are only RSA) than with other key formats. With V3 keys, the MPI bit count prefix (i.e., the first two octets) is not encrypted. Only the MPI non- prefix data is encrypted. Furthermore, the CFB state is resynchronized at the beginning of each new MPI value, so that the CFB block boundary is aligned with the start of the MPI data.
With V4 keys, a simpler method is used. All secret MPI values are encrypted in CFB mode, including the MPI bitcount prefix.
The 16-bit checksum that follows the algorithm-specific portion is the algebraic sum, mod 65536, of the plaintext of all the algorithm- specific octets (including MPI prefix and data). With V3 keys, the checksum is stored in the clear. With V4 keys, the checksum is encrypted like the algorithm-specific data. This value is used to check that the passphrase was correct.

Key Packet Variants
5.5.1.1. Public Key Packet (Tag 6)
A Public Key packet starts a series of packets that forms an OpenPGP key (sometimes called an OpenPGP certificate).
5.5.1.2. Public Subkey Packet (Tag 14)
A Public Subkey packet (tag 14) has exactly the same format as a Public Key packet, but denotes a subkey. One or more subkeys may be associated with a top-level key. By convention, the top-level key provides signature services, and the subkeys provide encryption services.
Note: in PGP 2.6.x, tag 14 was intended to indicate a comment packet. This tag was selected for reuse because no previous version of PGP ever emitted comment packets but they did properly ignore them. Public Subkey packets are ignored by PGP 2.6.x and do not cause it to fail, providing a limited degree of backward compatibility.
5.5.1.3. Secret Key Packet (Tag 5)
A Secret Key packet contains all the information that is found in a Public Key packet, including the public key material, but also includes the secret key material after all the public key fields.
5.5.1.4. Secret Subkey Packet (Tag 7)
A Secret Subkey packet (tag 7) is the subkey analog of the Secret Key packet, and has exactly the same format.
5.5.2. Public Key Packet Formats
There are two versions of key-material packets. Version 3 packets were first generated by PGP 2.6. Version 2 packets are identical in format to Version 3 packets, but are generated by PGP 2.5 or before. V2 packets are deprecated and they MUST NOT be generated. PGP 5.0 introduced version 4 packets, with new fields and semantics. PGP 2.6.x will not accept key-material packets with versions greater than 3.
OpenPGP implementations SHOULD create keys with version 4 format. An implementation MAY generate a V3 key to ensure interoperability with old software; note, however, that V4 keys correct some security deficiencies in V3 keys. These deficiencies are described below. An implementation MUST NOT create a V3 key with a public key algorithm other than RSA.
A version 3 public key or public subkey packet contains:
V3 keys SHOULD only be used for backward compatibility because of three weaknesses in them. First, it is relatively easy to construct a V3 key that has the same key ID as any other key because the key ID is simply the low 64 bits of the public modulus. Secondly, because the fingerprint of a V3 key hashes the key material, but not its length, which increases the opportunity for fingerprint collisions. Third, there are minor weaknesses in the MD5 hash algorithm that make developers prefer other algorithms. See below for a fuller discussion of key IDs and fingerprints.
typedef struct pgpPktKeyV4_s * pgpPktKeyV4 |
The version 4 format is similar to the version 3 format except for the absence of a validity period.
This has been moved to the signature packet. In addition, fingerprints of version 4 keys are calculated differently from version 3 keys, as described in section "Enhanced Key Formats."
A version 4 packet contains:
Algorithm Specific Fields for RSA public keys:
Algorithm Specific Fields for DSA public keys:
Algorithm Specific Fields for Elgamal public keys:
typedef struct pgpPktLdata_s pgpPktLdata |
5.8.
Marker Packet (Obsolete Literal Packet) (Tag 10)
An experimental version of PGP used this packet as the Literal packet, but no released version of PGP generated Literal packets with this tag. With PGP 5.x, this packet has been re-assigned and is reserved for use as the Marker packet.
The body of this packet consists of:
Such a packet MUST be ignored when received. It may be placed at the beginning of a message that uses features not available in PGP 2.6.x in order to cause that version to report that newer software is necessary to process the message.
typedef struct pgpPktOnepass_s * pgpPktOnepass |
5.4.
One-Pass Signature Packets (Tag 4)
The One-Pass Signature packet precedes the signed data and contains enough information to allow the receiver to begin calculating any hashes needed to verify the signature. It allows the Signature Packet to be placed at the end of the message, so that the signer can compute the entire signed message in one pass.
A One-Pass Signature does not interoperate with PGP 2.6.x or earlier.
The body of this packet consists of:
Note that if a message contains more than one one-pass signature, then the signature packets bracket the message; that is, the first signature packet after the message corresponds to the last one-pass packet and the final signature packet corresponds to the first one- pass packet.
typedef struct pgpPktPubkey_s pgpPktPubkey |
5.1.
Public-Key Encrypted Session Key Packets (Tag 1)
A Public-Key Encrypted Session Key packet holds the session key used to encrypt a message. Zero or more Encrypted Session Key packets (either Public-Key or Symmetric-Key) may precede a Symmetrically Encrypted Data Packet, which holds an encrypted message. The message is encrypted with the session key, and the session key is itself encrypted and stored in the Encrypted Session Key packet(s). The Symmetrically Encrypted Data Packet is preceded by one Public-Key Encrypted Session Key packet for each OpenPGP key to which the message is encrypted. The recipient of the message finds a session key that is encrypted to their public key, decrypts the session key, and then uses the session key to decrypt the message.
The body of this packet consists of:
Algorithm Specific Fields for RSA encryption
Algorithm Specific Fields for Elgamal encryption:
typedef union pgpPktSig_u * pgpPktSig |
5.2.
Signature Packet (Tag 2)
A signature packet describes a binding between some public key and some data. The most common signatures are a signature of a file or a block of text, and a signature that is a certification of a user ID.
Two versions of signature packets are defined. Version 3 provides basic signature information, while version 4 provides an expandable format with subpackets that can specify more information about the signature. PGP 2.6.x only accepts version 3 signatures.
Implementations MUST accept V3 signatures. Implementations SHOULD generate V4 signatures. Implementations MAY generate a V3 signature that can be verified by PGP 2.6.x.
Note that if an implementation is creating an encrypted and signed message that is encrypted to a V3 key, it is reasonable to create a V3 signature.

Symmetric-Key Encrypted Session-Key Packets (Tag 3)
The Symmetric-Key Encrypted Session Key packet holds the symmetric- key encryption of a session key used to encrypt a message. Zero or more Encrypted Session Key packets and/or Symmetric-Key Encrypted Session Key packets may precede a Symmetrically Encrypted Data Packet that holds an encrypted message. The message is encrypted with a session key, and the session key is itself encrypted and stored in the Encrypted Session Key packet or the Symmetric-Key Encrypted Session Key packet.
If the Symmetrically Encrypted Data Packet is preceded by one or more Symmetric-Key Encrypted Session Key packets, each specifies a passphrase that may be used to decrypt the message. This allows a message to be encrypted to a number of public keys, and also to one or more pass phrases. This packet type is new, and is not generated by PGP 2.x or PGP 5.0.
The body of this packet consists of:
typedef struct pgpPktTrust_s pgpPktTrust |
5.10.
Trust Packet (Tag 12)
The Trust packet is used only within keyrings and is not normally exported. Trust packets contain data that record the user's specifications of which key holders are trustworthy introducers, along with other information that implementing software uses for trust information.
Trust packets SHOULD NOT be emitted to output streams that are transferred to other users, and they SHOULD be ignored on any input other than local keyring files.
typedef struct pgpPktUid_s pgpPktUid |
5.11.
User ID Packet (Tag 13)
A User ID packet consists of data that is intended to represent the name and email address of the key holder. By convention, it includes an RFC 822 mail name, but there are no restrictions on its content. The packet length in the header specifies the length of the user id. If it is text, it is encoded in UTF-8.

5.2.3.1.
Signature Subpacket Specification
The subpacket fields consist of zero or more signature subpackets. Each set of subpackets is preceded by a two-octet scalar count of the length of the set of subpackets.
Each subpacket consists of a subpacket header and a body. The header consists of:
The length includes the type octet but not this length. Its format is similar to the "new" format packet header lengths, but cannot have partial body lengths. That is:
if the 1st octet < 192, then lengthOfLength = 1 subpacketLen = 1st_octet if the 1st octet >= 192 and < 255, then lengthOfLength = 2 subpacketLen = ((1st_octet - 192) << 8) + (2nd_octet) + 192 if the 1st octet = 255, then lengthOfLength = 5 subpacket length = [four-octet scalar starting at 2nd_octet]
The value of the subpacket type octet may be:
2 = signature creation time 3 = signature expiration time 4 = exportable certification 5 = trust signature 6 = regular expression 7 = revocable 9 = key expiration time 10 = placeholder for backward compatibility 11 = preferred symmetric algorithms 12 = revocation key 16 = issuer key ID 20 = notation data 21 = preferred hash algorithms 22 = preferred compression algorithms 23 = key server preferences 24 = preferred key server 25 = primary user id 26 = policy URL 27 = key flags 28 = signer's user id 29 = reason for revocation 100 to 110 = internal or user-defined
An implementation SHOULD ignore any subpacket of a type that it does not recognize.
Bit 7 of the subpacket type is the "critical" bit. If set, it denotes that the subpacket is one that is critical for the evaluator of the signature to recognize. If a subpacket is encountered that is marked critical but is unknown to the evaluating software, the evaluator SHOULD consider the signature to be in error.
