GnuPG Defaults

[Kevin Hilton]

I'm sure its probably contained in one of the RFC's, however when was
DSA signing keys and ElGamal Encryption keys, along with the AES-256
cipher and SHA1 digest chosen as the defaults for key generation?  Any
particular reasons these were chosen as the defaults?  (This is not an
attempt to lure people into a discussion of which is better than
that).  I'm just curious why these were chosen as defaults.
