Detailed Description

APIs to for RSA encryption/decryption and sign/verify using PKCS1 v1.5, OEAP and PSS.

These functions support RSA key setup and primitives.

Supported key sizes (in bits) are: size >= 1024, size = 2^n or 3 * 2^n. This includes the popular sizes: 1024, 2048, 3072, and 4096 bits.
