Package org.c02e.jpgpj.key
Class KeyForEncryption
java.lang.Object
org.c02e.jpgpj.Key
org.c02e.jpgpj.key.KeyForEncryption
- All Implemented Interfaces:
Cloneable
Key that should be used exclusively for encryption.
Regardless of PGP usage flags associated with the original key source,
only the last subkey flagged for encryption will be used, and the key will be
used for nothing else (so the Encryptor
will use this key only for
encryption, and not for signing; and the Decryptor
will ignore this
key entirely). If no subkeys have been flagged for encryption, this class
will automatically flag the subkey most likely to have been intended to be
used for encryption.
Use like the following:
new Encryptor(
new KeyForSigning(new File("path/to/my/keys/alice-sec.gpg"), "password123"),
new KeyForEncryption(new File("path/to/my/keys/bob-pub.gpg"))
).encrypt(
new File("path/to/plaintext.txt"),
new File("path/to/ciphertext.txt.gpg")
);
