## Detailed Description

5.2.2. Version 3 Signature Packet Format

The body of a version 3 Signature Packet contains:

- One-octet version number (3).
- One-octet length of following hashed material. MUST be 5.
  - One-octet signature type.
  - Four-octet creation time.
- Eight-octet key ID of signer.
- One-octet public key algorithm.
- One-octet hash algorithm.
- Two-octet field holding left 16 bits of signed hash value.
- One or more multi-precision integers comprising the signature.

Algorithm Specific Fields for RSA signatures:

- multiprecision integer (MPI) of RSA signature value m**d.

Algorithm Specific Fields for DSA and EdDSA signatures:

- MPI of DSA value r.
- MPI of DSA value s.
