Hi everyone, Since Eric urged me to pick some numbers for TLS-PSK soon, I decided to update the list of numbers currently in use (or at least proposed somewhere) from my earlier email in April. The list now contains more historical information; most of that work is presumably dead, and does not need to prevent future allocation of those numbers. (Corrections and additions are of course welcome!) Based on this, I'd suggest that TLS-PSK should use ciphersuite numbers starting from 0x8A (there are some unused holes before that, though), and alert number 115. Any objections or comments to that? While doing this, I also noticed some collisions: - TLS extension number 6 is used by both draft-ietf-tls-ecc-06 and draft-ietf-tls-srp-08. - TLS extension number 7 is used both by draft-ietf-tls-ecc-06 and draft-ietf-tls-openpgp-keys-05. - Ciphersuites 0x60-0x65 are proposed in draft-lee-tls-seed-00, but these numbers are used by "RSA1024" ciphersuites which are quite widely implemented. - Ciphersuites 0x50-0x58 are used in draft-ietf-tls-srp-08, but some OpenSSL versions use those for ECC (and these were also used in earlier versions of draft-ietf-tls-ecc). - Ciphersuites 0x77 and 0x78 are used in draft-ietf-openpgp-keys-05, but some OpenSSL versions use those for ECC.

[*11] These numbers were used in draft-ietf-tls-ntru-00 (Ari Singer, "NTRU Cipher Suites for TLS", July 2001), but presumably this work is dead and the numbers can be reused for other purposes. [*12] These numbers were used in draft-ietf-tls-ntru-00, but presumably this work is dead, and and many of the numbers are widely used for other purposes anyway. [*13] These numbers were used in draft-ietf-tls-pathsec-00 (Joseph Hui, "TLS Pathsec Protocol", September 2001), but presumably this work is dead, and the numbers can be used for other purposes. [*14] These numbers were used in draft-ietf-tls-openpgp-02 (Will Price and Michael Elkins, "Extensions to TLS for OpenPGP keys", February 2002), but presumably this work is dead, and the numbers can be used for other purposes.
