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. The AES block cipher is used in CBC mode for symmetric encryption; RSA for asymmetric (public key) encryption. High-level envelope methods 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.
