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
I have blogged about GNU SASL and GS2-KRB5 with the native Kerberos on Mac OS X before, so the next logical step has been to support GS2-KRB5 on Windows through MIT Kerberos for Windows (KfW). With the latest release of Continue reading GS2-KRB5 using GNU SASL and MIT Kerberos for Windows
Yesterday (12th July 2010) the RFC editor announced the publication of RFC 5801, which I’m co-author of. The GS2 document has taken 5 years to reach this status, see my page on GS2 status. So what is GS2?
I have worked in the IETF on the specification for the next generation GSSAPI-to-SASL bridge called GS2 (see my status page for background) for a couple of years now. The specification is (finally!) in the RFC editor’s queue, and is Continue reading GS2-KRB5 in GNU SASL 1.5.0
I have read Russel Coker’s nice article on identifying use of thread unsafe functions. This reminded me of a script I wrote a long time ago that is part of GNU SASL‘s regression suite: threadsafety. As you can see, my Continue reading Thread Safe Functions
Sometimes it can be useful to build things without the autoconf ./configure machinery, and just use a simple and hand-maintained makefile and config.h. This is needed to build things in older uClinux environments. I wrote some instructions on how to Continue reading Building GnuTLS and GNU SASL without running ./configure
Building software for embedded systems is quite simple today. A returning customer asked me to clarify how to build gsasl and gnutls under uClinux, and I finally created a web page collecting the instructions and patch. http://josefsson.org/uclinux/
