java-pgp's Issues

[Solved] Exception in thread "main" java.io.IOException: unknown PGP public key algorithm encountered

hello! thanks for making this repo. I was writing an issue because I was struggling to get the code working but as I was writing this, I finally managed to get it running on my own. It might nonetheless be useful to someone running into the same issue.

Long story short, generate the public and private keys using:

gpg --full-generate-key

then when prompted:

Please select what kind of key you want:
   (1) RSA and RSA
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)
   (9) ECC (sign and encrypt) *default*
  (10) ECC (sign only)

Select 1 or 2 or 4, but do not select 3, 9, or 10. The default choice being 9, it does not work with the default.
Otherwise, you will run into this error (when using 9 or 10,):

java.io.IOException: unknown PGP public key algorithm encountered

Or this error (when using 3):

java.lang.IllegalArgumentException: Can't find public key in the key ring.

Unknown packet type encountered: 20

Getting an error at line 165. of method decryptFile()

Can you provide a sample encrypted file?
