Private Key Parsing #174

Open nodh opened 3 weeks ago

nodh commented 3 weeks ago

Implement parsing private key from PEM representation, e.g. from this input to an object in Signum.

-----BEGIN PRIVATE KEY-----

-----END PRIVATE KEY-----

@iaik-jheher just to double-check: that's a new key, works and behaves as the ephemeral key, only it's not generated, but loaded from external data. I smell boilerplate code from the future

iaik-jheher commented 3 weeks ago

Yes, sounds about right. Signer.ForPEMEncodedPrivateKey?

iaik-jheher commented 3 weeks ago

Ideally we'd want data classes for encoded private keys though...

I would really need this for verification of samples from specs. Key is defined in PKCS#1 or PKCS#8 format, e.g.:

PKCS#1:

-----BEGIN EC PRIVATE KEY-----
MHcCAQEEIGwHU3LKj2fCxiUWB76jCnxIOJ2KAgYKbYGays8h/g+goAoGCCqGSM49
AwEHoUQDQgAET+Zr8vrF+kdr1zpjK3ufUv1fd7DS0s8Yf8/Ny3Hb4I57Sz20Zabp
brDmqFB7AmrWhdejOPHn9+Ln51i42bCdGQ==
-----END EC PRIVATE KEY-----

and PKCS#8:

-----BEGIN PRIVATE KEY-----
MIGHAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBG0wawIBAQQgbAdTcsqPZ8LGJRYH
