I’m pleased to announce Guile-Gcrypt version 0.3.0:

  git clone https://notabug.org/cwebber/guile-gcrypt.git
  cd guile-gcrypt
  git checkout v0.3.0  # or 99381361c5ec081fa691a536e8687ffd89897119
  git tag -v v0.3.0

The ‘git tag -v’ command checks the authenticity of your checkout.
You may need to retrieve the signing key first:

  gpg --keyserver pool.sks-keyservers.net \
      --recv-keys 3CE464558A84FDC69DB40CFB090B11993D9AEBB5

Guile-Gcrypt provides Guile 3.0/2.x bindings to the GNU Libgcrypt
cryptography library.  It provides modules for cryptographic hash
functions, message authentication codes (MAC), public-key cryptography,
strong randomness, and more.

Excerpt from the ‘NEWS’ file:

  * Changes in 0.3.0 (since 0.2.1)

  ** ‘sexp->canonical-sexp->sexp’ now accepts integers
  ** (gcrypt common) exports ‘error/’ constants and error handling procedures
  ** ‘verify’ now throws upon errors other than ‘error/bad-signature’
  ** (gcrypt hmac) and (gcrypt hash) export bindings for their syntax literals
  ** New ‘hash-algorithm-name’ and ‘mac-algorithm-name’ procedures

Guile-Gcrypt does not currently wrap all the Libgcrypt API.  Your help
in improving it is very welcome!  For bug reports and patches, see:

Plain email to Chris or myself or guile-user would also work fine.  :-)
