In libgpg-error/doc/errorref.txt, it says:

	18	GPG_ERR_WRONG_SECKEY		Wrong secret key used

In the code of GnuPG, this error occurs when decryption by your
private key is finished to get the secret session key, but the result
of the secret session key is found malformed.

I'm reading gnupg/g10/pubkey-enc.c.
