- Update to version 3.2.0 * Added implementation of the DHEat denial-of-service attack (see --dheat option; CVE-2002-20001). * Expanded filter of CBC ciphers to flag for the Terrapin vulnerability. It now includes more rarely found ciphers. * Fixed parsing of ecdsa-sha2-nistp* CA signatures on host keys. Additionally, they are now flagged as potentially back-doored, just as standard host keys are. * Gracefully handle rare exceptions (i.e.: crashes) while performing GEX tests. * Built-in policies now include a change log (use -L -v to view them). * Custom policies now support the allow_algorithm_subset_and_reordering directive to allow targets to pass with a subset and/or re-ordered list of host keys, kex, ciphers, and MACs. This allows for the creation of a baseline policy where targets can optionally implement stricter controls; * Custom policies now support the allow_larger_keys directive to allow targets to pass with larger host keys, CA keys, and Diffie-Hellman keys. This allows for the creation of a baseline policy where targets can optionally implement stricter controls * Color output is disabled if the NO_COLOR environment variable is set (see https://no-color.org/). * Added 1 new key exchange algorithm: gss-nistp384-sha384-*. * Added 1 new cipher: aes128-ocb@libassh.org.

(revision 15)
- Update to version 3.3.0 * Results from concurrent scans against multiple hosts are no longer improperly combined. * Hostname resolution failure no longer causes scans against multiple hosts to terminate unexpectedly. * Algorithm recommendations resulting from warnings are now printed in yellow instead of red. * Added failure, warning, and info notes to JSON output (note that this results in a breaking change to the banner protocol, "enc", and "mac" fields). * Fixed crash during GEX tests. * Refined GEX testing against OpenSSH servers: when the fallback mechanism is suspected of being triggered, perform an additional test to obtain more accurate results. * The color of all notes will be printed in green when the related algorithm is rated good. * Prioritized host key certificate algorithms for Ubuntu 22.04 LTS client policy. * Marked all NIST K-, B-, and T-curves as unproven since they are so rarely used. * Added built-in policy for OpenSSH 9.4. * Added 12 new host keys * Added 15 new key exchanges. * Added 8 new ciphers. * Added 14 new MACs.

- Update to version 2.9.0 * Dropped support for Python 3.6 * Updated CVE database. * Added -g and --gex-test for granular GEX modulus size tests. * JSON 'target' field now always includes port number. * JSON output now includes recommendations and CVE data. * Mixed host key/CA key types (i.e.: RSA host keys signed with ED25519 CAs, etc.) are now properly handled. * Warnings are now printed for 2048-bit moduli. * SHA-1 algorithms now cause failures. * CBC mode ciphers are now warnings instead of failures. * Generic failure/warning messages replaced with more specific reasons (i.e.:'using weak cipher' => 'using broken RC4 cipher') * Updated built-in policies to include missing host key size information. * Added built-in policies for OpenSSH 8.8, 8.9, 9.0, 9.1, 9.2, and 9.3. * Added 33 new host keys. * Added 46 new key exchanges. * Added 28 new ciphers. * Added 5 new MACs.

- Update to version 2.5.0 * Fixed crash when running host key tests. * Handles server connection failures more gracefully. * Now prints JSON with indents when -jj is used (useful for debugging). * Added MD5 fingerprints to verbose output. * Added -d/--debug option for getting debugging output. * Updated JSON output to include MD5 fingerprints. Note that this results in a breaking change in the 'fingerprints' dictionary format. * Updated OpenSSH 8.1 (and earlier) policies to include rsa-sha2-512 and rsa-sha2-256. * Added OpenSSH v8.6 & v8.7 policies. * Added 3 new key exchanges: + gss-gex-sha1-eipGX3TCiQSrx573bT1o1Q== + gss-group1-sha1-eipGX3TCiQSrx573bT1o1Q== + gss-group14-sha1-eipGX3TCiQSrx573bT1o1Q== * Added 3 new MACs: + hmac-ripemd160-96 + AEAD_AES_128_GCM + AEAD_AES_256_GCM

- Update to version 2.4.0 * Added multi-threaded scanning support. * Added version check for OpenSSH user enumeration (CVE-2018-15473). * Added deprecation note to host key types based on SHA-1. * Added extra warnings for SSHv1. * Added built-in hardened OpenSSH v8.5 policy. * Upgraded warnings to failures for host key types based on SHA-1 * Fixed crash when receiving unexpected response during host key test. * Fixed hang against older Cisco devices during host key test & gex test. * Fixed improper termination while scanning multiple targets when one target returns an error. * Dropped support for Python 3.5 (which reached EOL in Sept.2020) * Added 1 new key exchange: sntrup761x25519-sha512@openssh.com.

- Update to version 2.3.1 * Now parses public key sizes for rsa-sha2-256-cert-v01@openssh.com and rsa-sha2-512-cert-v01@openssh.com host key types. * Flag ssh-rsa-cert-v01@openssh.com as a failure due to SHA-1 hash. * Fixed bug in recommendation output which suppressed some algorithms inappropriately. * Built-in policies now include CA key requirements (if certificates are in use). * Lookup function (--lookup) now performs case-insensitive lookups of similar algorithms. * Migrated pre-made policies from external files to internal database. * Split single 3,500 line script into many files (by class). * Added setup.py support * Added 1 new cipher: des-cbc@ssh.com. - Install manpage - Use py-* rpm macros - Update to version 2.3.0

- Update to versino 2.3.0 The highlight of this release is support for policy scanning (this allows an admin to test a server against a hardened/standard configuration). * Added new policy auditing functionality to test adherence to a hardening guide/standard configuration (see -L/--list-policies, -M/--make-policy and -P/--policy). * Created new man page (see ssh-audit.1 file). * 1024-bit moduli upgraded from warnings to failures. * Many Python 2 code clean-ups, testing framework improvements, pylint & flake8 fixes, and mypy type comments. * Added feature to look up algorithms in internal database (see --lookup) * Suppress recommendation of token host key types. * Added check for use-after-free vulnerability in PuTTY v0.73. * Added 11 new host key types: ssh-rsa1, ssh-dss-sha256@ssh.com, ssh-gost2001, ssh-gost2012-256, ssh-gost2012-512, spki-sign-rsa, ssh-ed448, x509v3-ecdsa-sha2-nistp256, x509v3-ecdsa-sha2-nistp384, x509v3-ecdsa-sha2-nistp521, x509v3-rsa2048-sha256. * Added 8 new key exchanges: diffie-hellman-group1-sha256, kexAlgoCurve25519SHA256, Curve25519SHA256, gss-group14-sha256-, gss-group15-sha512-, gss-group16-sha512-, gss-nistp256-sha256-, gss-curve25519-sha256-. * Added 5 new ciphers: blowfish, AEAD_AES_128_GCM, AEAD_AES_256_GCM, crypticore128@ssh.com, seed-cbc@ssh.com. * Added 3 new MACs: chacha20-poly1305@openssh.com, hmac-sha3-224, crypticore-mac@ssh.com. - Update ssh-audit.keyring
