In a previous post I’ve introduced a new Common Lisp system for parsing command-line options named clingon.

Not long ago I’ve decided I would spend more time with Common Lisp. This is how my journey in the world of Common Lisp started.

If you are running SLIME with SBCL on macOS you may notice that the REPL output seems to experience a bit of delay when compared to other implementations like Clozure CL or ECL for example.

I’ve always been fascinated by old retro computers, even though I didn’t have one, so it is hard for me to explain why I feel such a connection with these old machines.

RSASSA-PKCS1-v1_5 signature scheme with Appendix is defined as part of RFC 8017.

This is a follow up of my previous post about parsing and generating OpenSSH keys in Common Lisp.

Native support for bcrypt password hashes was somewhat missing in the Common Lisp ecosystem, unless you count the various CFFI wrappers.

Support for ECDSA private and public keys in ironclad has been implemented.

In previous posts I’ve discussed how you can decode and encode data in RFC 4251 binary format using Common Lisp.

Public key fingerprint represents the identity of a public key, which you get after applying a hashing function to the binary blob that makes up a public key.
