-----------------------------------
Summary: PGP decryption sometimes can't find the secret key
Key: CAMEL-7106
URL: https://issues.apache.org/jira/browse/CAMEL-7106
Project: Camel
Issue Type: Bug
Components: camel-crypto
Affects Versions: 2.12.2
Reporter: Mark Riordan
Camel Crypto fails to decrypt PGP files encrypted by GnuPG and other programs,
when the secret key used to encrypt the symmetric key is not the first on the
keyring (using Bouncy Castle's definition of a keyring). The error message is
"Provided input is encrypted with unknown pair of keys." Since the encryption
key in files from other PGP programs normally is a subkey and is not the first
one in the keyring (which is typically the master key), this means that
decryption fails in many cases.
The fix is a one-liner to PGPDataFormatUtil.findPrivateKeyWithKeyId(), to use a
BC method that searches for the secret key rather than assume it's the first
one on the secret keyring. I will attach a patch.
