-<p>Some additionnal ciphers got added later on, but this basically mean that you cannot be sure that a OpenPGP message you sent wasn’t done in more-or-less plaintext. 3DES was broken by the EFF in 199x, SHA1 was probably still known as okay but could be better (as SHA2 was already a thing), DSA was probably not now enough as good to be hardcoded, no idea for Elgamal.</p><!-- FIXME -->

DES was broken by the EFF in 199x, 3DES is basically now on about the same size (NIST: 80 bits of security) but computing power got much better, SHA1 was probably still known as okay but could be better (as SHA2 was already a thing), DSA was probably not now enough as good to be hardcoded, no idea for Elgamal.</p><!-- FIXME -->
