pgpainless: Catch KEY MISMATCH exception

Let’s imagine that we have the following case:

create an encrypted text for key A and key B.
we have key C
we try to decrypt the encrypted text with key C
after 3. we will receive the following exception org.bouncycastle.openpgp.PGPException: Decryption failed - No suitable decryption key or passphrase found that relates to the following code

On the user side it can mean that the user uses the wrong key for decryption (didn’t import the right key)

it would be great to have for example KeyMismatchException that cover the following

@vanitasvitae What do you think about that?

got it. in that case, for our sense, the callback here would not be used, since we always provide all keys anyway

Secret key passphrases are handled elsewhere, namely in the SecretKeyRingProtector. The CachingSecretKeyRingProtector has support for asking for missing key passphrases : https://github.com/pgpainless/pgpainless/blob/master/ pgpainless-core/src/main/java/org/pgpainless/key/protection/ CachingSecretKeyRingProtector.java)
