ecc_tools

Elliptic-curve cryptography tools

Usage

• ECC raw keygen

  ecc_tools keygen pubkey_file privkey_file   # ECC-384 only, strong enough

• Hash gen

  dd if=/dev/urandom of=hash_file bs=1 count=48 status=none   # 48 Bytes = 384 bits, ECC-384
  # -- or --
  sha256sum filename.ext | cut -d ' ' -f 1 |  xxd -r -p > hash_file

• ECC Sign

  ecc_tools sign pubkey_file privkey_file hash_file signature_file

• ECC Verify

  ecc_tools verify pubkey_file hash_file signature_file
