Toolkit for Encryption, Signatures and Certificates Based on OpenSSL
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.
