I’m pleased to announce Guile-Gcrypt version 0.4.0:

  git clone https://notabug.org/cwebber/guile-gcrypt.git
  cd guile-gcrypt
  git checkout v0.4.0  # or 425554d4327eeeb60c39e3d4a1b7bc5e36b63953
  git tag -v v0.4.0

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 0.4.0 (since 0.3.0)
  ** ‘base64-encode’ and ‘base64-decode’ now let you optionally control padding
  ** New supported algorithms added to (gcrypt hash)
  ** New supported algorithms added to (gcrypt mac)
  ** Improvements and fixes to the manual

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.  :-)
