Python EVP_MD_CTX_cleanup Examples

Example #1

 def _digest(self, space):
     with lltype.scoped_alloc(ropenssl.EVP_MD_CTX.TO) as ctx:
         with self.lock:
             ropenssl.EVP_MD_CTX_copy(ctx, self.ctx)
         digest_size = self.digest_size
         with rffi.scoped_alloc_buffer(digest_size) as buf:
             ropenssl.EVP_DigestFinal(ctx, buf.raw, None)
             ropenssl.EVP_MD_CTX_cleanup(ctx)
             return buf.str(digest_size)
