* common/ssh-utils.c (get_fingerprint): Handle the prefix of 0x40. * common/t-ssh-utils.c (sample_keys): Add a new key. -- Also adding Ed25519 test key.
2015-09-22ssh: Fix fingerprint computation for 384 bit ECDSA keys.Werner Koch1-1/+1
* common/ssh-utils.c (get_fingerprint): Fix hashed string. -- That was an obvious c+p bug which should have been caught by a test case. GnuPG-bug-id: 2075 Debian-bug-id: 795636
2014-03-22agent: Cleanups to prepare implementation of Ed25519.Werner Koch1-38/+103
* agent/cvt-openpgp.c: Remove. (convert_to_openpgp): Use gcry_sexp_extract_param. * agent/findkey.c (is_eddsa): New. (agent_is_dsa_key, agent_is_eddsa_key): Check whether ecc means EdDSA. * agent/pksign.c (agent_pksign_do): Add args OVERRIDEDATA and OVERRIDEDATALEN. * common/ssh-utils.c (is_eddsa): New. (get_fingerprint): Take care or EdDSA.
2012-12-12ssh: Support ECDSA keys.Werner Koch1-0/+28
* agent/command-ssh.c (SPEC_FLAG_IS_ECDSA): New. (struct ssh_key_type_spec): Add fields CURVE_NAME and HASH_ALGO. (ssh_key_types): Add types ecdsa-sha2-nistp{256,384,521}. (ssh_signature_encoder_t): Add arg spec and adjust all callers. (ssh_signature_encoder_ecdsa): New. (sexp_key_construct, sexp_key_extract, ssh_receive_key) (ssh_convert_key_to_blob): Support ecdsa. (ssh_identifier_from_curve_name): New. (ssh_send_key_public): Retrieve and pass the curve_name. (key_secret_to_public): Ditto. (data_sign): Add arg SPEC and change callers to pass it. (ssh_handler_sign_request): Get the hash algo from SPEC. * common/ssh-utils.c (get_fingerprint): Support ecdsa. * agent/protect.c (protect_info): Add flag ECC_HACK. (agent_protect): Allow the use of the "curve" parameter. * agent/t-protect.c (test_agent_protect): Add a test case for ecdsa. * agent/command-ssh.c (ssh_key_grip): Print a better error code. -- The 3 standard curves are now supported in gpg-agent's ssh-agent protocol implementation. I tested this with all 3 curves and keys generated by OpenSSH 5.9p1. Using existing non-ssh generated keys will likely fail for now. To fix this, the code should first undergo some more cleanup; then the fixes are pretty straightforward. And yes, the data structures are way too complicated.
2012-04-20Change license for some files in common to LGPLv3+/GPLv2+.Werner Koch1-5/+15
Having the LGPL on the common GnuPG code helps to share code between GnuPG and related projects (like GPGME and Libassuan).
