Cannot create encrypted file #32

Hi Justin,

I've been looking at how to use your library to encrypt avro messages, and when launching my code, an exception appears:

Exception in thread "main" org.bouncycastle.openpgp.PGPException: no suitable signing key found at org.c02e.jpgpj.Encryptor.sign(Encryptor.java:982) at org.c02e.jpgpj.Encryptor.prepareCiphertextOutputStream(Encryptor.java:773) at org.c02e.jpgpj.Encryptor.encrypt(Encryptor.java:691) at org.c02e.jpgpj.Encryptor.encrypt(Encryptor.java:662) at avro.EncryptPayload$.main(EncryptPayload.scala:40) at avro.EncryptPayload.main(EncryptPayload.scala)

I have created the pair of keys using gpg:

gpg --gen-key

gpg --armor --output public-key.gpg --export my-email@gmail.com

Then I exported public-key.gpg to src/main/resources and compile this code

Could you help me?

If you want to encrypt without signing, set the signing algorithm to unsigned:

encryptor.setSigningAlgorithm(HashingAlgorithm.Unsigned);

If you want to encrypt and sign with the same key, you need to the keypair's secret key (export it from gpg with the --export-secret-keys flag), and you also need to supply its passphrase:

new Encryptor(new Key(new File("src/main/resources/secret-key.gpg"), "password123"))

I can encrypt the file using unsigned. It is ok for me. Now I have to decrypt the same file, but that is another question.
