@end smallexample

@majorheading 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.
