My advice would be to avoid specific support for any *particular*
digest algorithm. Instead, provide bindings to:
- EVP_get_digestbyname(),
- EVP_MD_CTX_create(3),
- EVP_DigestInit_ex(3),
- EVP_DigestUpdate(3),
- EVP_DigestFinal_ex(3),
- EVP_MD_CTX_destroy(3)
which can they use *any* available digest algorithm (by name).
