pgp encryption functions

From

Hello,
I'm trying to use the pgp_pub_encrypt and pgp_pub_decrypt_bytea
functions to store some data in my db.

This is how I encrypt:

INSERT INTO "Test"(
            "test")
    VALUES (pgp_pub_encrypt('test', dearmor('-----BEGIN PGP PUBLIC KEY
BLOCK-----
Version: GnuPG v2.0.12 (MingW32)

mQENBErk2KkBCAC.... (public key block) ...
-----END PGP PUBLIC KEY BLOCK-----
')));

And this is how I try to decrypt:

SELECT pgp_pub_decrypt_bytea(bytea ("test"), dearmor('-----BEGIN PGP
PRIVATE KEY BLOCK-----
Version: GnuPG v2.0.12 (MingW32)

lQO+BErk2KkBC... (private key block) ...
-----END PGP PRIVATE KEY BLOCK-----
'), 'ktulu3437')  --> this is the passphrase
  FROM "Test";

Encryptions works fine, but the decrypting returns "Corrupt data".
What am I doing wrong?

Christian Petzold.

- if this is the SQL you test with, make sure the table is empty...

- this message may also appear if the passphrase for secret key is wrong.
  [this needs fixing]

- make sure the secret key really corresponds to public key

If none of these fix your problem, please send repeatable test-case
(with temp key).
