- # SYNOPSIS
- #
- # AX_LIB_CRYPTO([yes|no|auto])
- #
- # DESCRIPTION
- #
- # Searches for the 'crypto' library with the --with... option.
- #
- # If found, define HAVE_CRYPTO and macro CRYPTO_LIBS. Also defines
- # CRYPTO_WITH_<algo> for the algorithms found available. Possible
- # algorithms: AES BF CAMELLIA CAST DES IDEA RC2 RC5 MD2 MD4 MD5 SHA RIPEMD
- # RSA DSA DH
- #
- # The argument is used if no --with...-crypto option is set. Value "yes"
- # requires the configuration by default. Value "no" does not require it by
- # default. Value "auto" configures the library only if available.
- #
- # See also AX_LIB_BEECRYPT and AX_LIB_GCRYPT.
