Detailed Description

RSA key setup, for 1024 and 2048 bit keys.

These functions support the setup of 1024 and 2048 RSA secret and public keys.

Remarks

1024 bit keys are no longer considered secure; use of at least 2048 bit keys is recommended.

This is the original ocrypto API for RSA. See the newer API that supports additional key sizes.
