KeyczarKeyczar is an open source cryptographic toolkit designed to make it easier and safer for devlopers to use cryptography in their applications. Keyczar supports authentication and encryption with both symmetric and asymmetric keys. Keyczar was originally developed by members of the Google Security Team.
This hybrid approach is necessary because encrypting more than n/8-11 bytes with an asymmetric key is considered insecure, so the asymmetric key encrypts a generated key for a symmetric block cipher.Return a through stream enc that takes cleartext as input and produces ciphertext as output encrypted with a public key buffer or string publicKey in PEM or ssh-style format.
Bulwark is a native Node.js addon that utilizes the RSA PKCS#11 API (v2.20) to perform cryptographic operations. This module, specifically, acts as a common layer upon which various vendor-specific additions can be made. Bulwark utilizes tjfontaine's excellent node-addon-layer which provides a nice Node.js add-on interface for C. This allows us to avoid writing the add-on in C++.
