Detailed Description

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:

• A one-octet version number (4).
• A four-octet number denoting the time that the key was created.
• A one-octet number denoting the public key algorithm of this key
• A series of multi-precision integers comprising the key material. This algorithm-specific portion is:

Algorithm Specific Fields for RSA public keys:

• multiprecision integer (MPI) of RSA public modulus n;
• MPI of RSA public encryption exponent e.

Algorithm Specific Fields for DSA public keys:

• MPI of DSA prime p;
• MPI of DSA group order q (q is a prime divisor of p-1);
• MPI of DSA group generator g;
• MPI of DSA public key value y (= g**x where x is secret).

Algorithm Specific Fields for Elgamal public keys:

• MPI of Elgamal prime p;
• MPI of Elgamal group generator g;
• MPI of Elgamal public key value y (= g**x where x is secret).
