Re: where to start the study of the principle of Cryptography
recommend you several books to read.
(1)Handbook of Applied Cryptography.
(2)Cryptographic Engineering.
(3)Guide to Elliptic Curve Cryptography - D. Hankerson, A. Menezes, S. Vanstone.

Re: Tool - ECDSA Sign/Verify features
(1)I'm not very clear with your question, but you can see if I make the right guesses: You want to call an ECDSA_sign interface make a ecdsa signature,using parameters(private key of key pair, Hm, ecc curve parameters secp256k1),but there is parameter K, you don't know how to deal with it. Then you ...

Re: ISO/IEC 9797-1
MAC Algorithm 1 works like the CBC mode of block cipher, with the IV equals to zero. Step 1 (padding): there are three methods to choose, any one is okay. Step 2 (splitting): split the padded data to q blocks D1,...,Dq. Step 3 (initial transformation): using the block cipher key K to encrypt the fir...
