With the release of Libntlm version 1.8 the release tarball can be reproduced on several distributions. We also publish a signed minimal source-only tarball, produced by git-archive which is the same format used by Savannah, Codeberg, GitLab, GitHub and others.

GSS-API is a standardized framework that is used by applications to, primarily, support Kerberos V5 authentication. GSS-API is standardized by IETF and supported by protocols like SSH, SMTP, IMAP and HTTP, and implemented by software projects such as OpenSSH, Exim, Continue reading Towards pluggable GSS-API modules
Simple Authentication and Security Layer (SASL, RFC4422) is the framework that was abstracted from the IMAP and POP protocols. Among the most popular mechanisms are PLAIN (clear-text passwords, usually under TLS), CRAM-MD5 (RFC2195), and GSSAPI (for Kerberos V5). The DIGEST-MD5 Continue reading What’s wrong with SCRAM?
The RFC Editor has announced a new document, RFC 6070, with test vectors for PKCS5 PBKDF2. The document grow out of my implementation of SCRAM for GNU SASL. During interop testing, more than one other implementation turned out to have Continue reading On Password Hashing and RFC 6070
I have finished the SCRAM implementation in GNU SASL. The remaining feature to be added were support for the “enhanced” SCRAM-SHA-1-PLUS variant instead of just the normal SCRAM-SHA-1 mechanism. The difference is that the latter supports channel bindings to TLS, Continue reading GNU SASL with SCRAM-SHA-1-PLUS
