Toolkit for Encryption, Signatures and Certificates Based on
OpenSSL
Description
Bindings to OpenSSL libssl and libcrypto, plus custom SSH key parsers.
Supports RSA, DSA and EC curves P-256, P-384, P-521, and curve25519. Cryptographic
signatures can either be created and verified manually or via x509 certificates.
AES can be used in cbc, ctr or gcm mode for symmetric encryption; RSA for asymmetric
(public key) encryption or EC for Diffie Hellman. 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.
