Subject: ‘guix authenticate’ failure in C locale
Date: Tue, 22 Apr 2014 10:51:34 +0200
As seen in <http://hydra.gnu.org/build/54212>, ‘guix authenticate’ could
fail when running in the C locale (as is the case on hydra.gnu.org):

The problem was that it could in some cases produce a signature sexp
with an invalid hash value.  For example:

  guix  archive --export /gnu/store/hyr8lvpbl2lbbkvr5v1qa25895bpcxls-gmp-6.0.0a-guile-builder

would produce an archive with a signature sexp like this (literally):

  (signature 
   (data 
    (flags pkcs1)
    (hash sha256 "^?\vU????{N4?`??eL??x???|1y????{L")
    )

  [...]

The problem is that the hash value shown here is the result of
substituting non-ASCII characters with question marks and other things.
Obviously signature verification on such a thing would fail, leading to
errors like the one above.

This could happen in some cases, when libgcrypt would choose to use a
byte string representation instead of a hexadecimal string, and is due
to the fact that ‘string->canonical-sexp’ would convert strings passed
to ‘gcry_sexp_new’ to locale encoding.

This is fixed with commit 6030d84 (see that commit for a concrete
example.)

A related issue is the choice of the stdout encoding used by ‘guix
authenticate’, fixed in 6f69588.

This appears to solve this bug.
