Hi , I am trying to used Nettle cryptolibrary. I download the source, installed on ubuntu wrote a some sample application using the readme, examples files.
There are couple of thing which i am still unsure. Can you help me understand this.
1. Does nettle support on PKCS1 encoding fro RSA encrytpion and signing? 2. In the PrivateKey structure, Is the d ( private expoenent ) never used? Does nettle use private key in CRT format only? and not in expoenent format ( i.e modulus and priv exp)
I would be glad if you can clarify this to me.

Yes, if you are asking about the padding used internally. The resulting signatures are simply represented as mpz_t bignums, and you have to encode and decode them to the representation you need for your protocol or file format of interest.
- In the PrivateKey structure, Is the d ( private expoenent ) never

It's not used. It is set by rsa_generate_keypair, though.
