This is a tool I've made to practice python and Cryptography.
1 generate rsa,ecc keys
2 sign a file with rsa/ecc private key, and different hash methods
3 verify a signature using rsa/ecc public key
4 encrypt with rsa public key
5 decrypt with rsa private key
1 less parameters which means easy to use (-i -o -s --priv --pub)
2 easy to extend (sign_vrfy enc_dec)
3 pycryptodome
use rsa to sign and verify file
use ecc to sign and verify file
use rsa to encrypt and decrypt file
