Class: OnePassSignaturePacket

OnePassSignaturePacket()

Implementation of the One-Pass Signature Packets (Tag 4)

RFC4880 5.4: 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.

Constructor

new OnePassSignaturePacket()

Members

flags

A one-octet number holding a flag showing whether the signature is nested. A zero value indicates that the next packet is another One-Pass Signature packet that describes another signature to be applied to the same message data.

Source:

hashAlgorithm :enums.hash

A one-octet number describing the hash algorithm used.

Type:
  • enums.hash
Source:
See:

issuerFingerprint

Only for v6 packets, 32 octets of the fingerprint of the signing key.

Source:

issuerKeyID

Only for v3 packets, an eight-octet number holding the Key ID of the signing key.

Source:

publicKeyAlgorithm :enums.publicKey

A one-octet number describing the public-key algorithm used.

Type:
  • enums.publicKey
Source:
See:

salt

Only for v6, a variable-length field containing the salt.

Source:

signatureType :enums.signature

A one-octet signature type. Signature types are described in RFC4880 Section 5.2.1.

Type:
  • enums.signature
Source:

version

A one-octet version number. The current versions are 3 and 6.
