Mode 1 : Attack RSA (specify --publickey or n and e)
- publickey : public rsa key to crack. You can import multiple public keys with wildcards.
- uncipher : cipher message to decrypt
- private : display private rsa key if recovered
Mode 2 : Create a Public Key File Given n and e (specify --createpub)
- n : modulus
- e : public exponent
Mode 3 : Dump the public and/or private numbers (optionally including CRT parameters in extended mode) from a PEM/DER format public or private key (specify --dumpkey)
- key : the public or private key in PEM or DER format
