Supported Algorithms/Key Format

Hi *,

My name is Malik and I just started using the Nettle.

I am looking for APIs for RSA crypto operations.

From rsa.h header file, I can make out that Nettle supports,

- RSA crypto APIs only for PKCS#1 v1.5 padding mechanisms and - CRT format for RSA private key

My questions, - Does nettle not support PKCS#1 v2.1 padding mechanisms e.g. RSASSA-PSS? - Does nettle not support exponent format for private key?. Meaning private key is made up of modulus and private exponent. - Is there an API for raw RSA crypto operation? Raw meaning, API must not do any encoding with input data but just has to sign/encrypt it.

Can someone please clarify my questions? Thanks very much indeed in advance for the clarifications.

Regards, Malik
