Toolkit for Encryption, Signatures and Certificates Based on
OpenSSL
Description
Bindings to OpenSSL libssl and libcrypto, plus custom SSH pubkey parsers.
Supports RSA, DSA and NIST curves P-256, P-384 and P-521. Cryptographic signatures
can either be created and verified manually or via x509 certificates. AES block
cipher is used in CBC mode for symmetric encryption; RSA for asymmetric (public key)
encryption. High-level envelope functions combine RSA and AES for encrypting arbitrary
sized data. Other utilities include key generators, hash functions (md5, sha1, sha256,
etc), base64 encoder, a secure random number generator, and 'bignum' math methods for
manually performing crypto calculations on large multibyte integers.
