Elliptic Curve Cryptography for public key encryption and ECDSA. Elliptic Cryptography Diffie Hellman Key Exchange with AES algorithms are implmented as well as Sha512

ECIES, ECDSA, HMAC, ECC Public Key Generation

Jul 16, 2022

Algorithms:

Elliptic Cryptography Integrated Encrypton Scheme

Elliptic Cryptography Digital Signature Algorithm

ECDSA Public Key Recovery from SEC 1, ver 1.9, section 4.1.6

Hash-based Message Authentication Code

Advanced Encryption Standard

512-bit Secure Hashing Algorithm

Only Weiestress curve is used

Only prime field sizes are supported

Curves: secp521r1, secp256k1 (Bitcoin Curve), secp256r1

Not For Professional use

Note: Public Key Recovery doesn't always work, further tests will be done

Currently, further improvements on Public Key Recovery as well as support of Binary Galois Fields GF(2^m) is being implemented
