[pkg-cryptsetup-devel] Bug#844050: cryptsetup: /lib/cryptsetup/scripts/decrypt_ssl throws away the key it has just decrypted

[g1]

Package: cryptsetup
Version: 2:1.6.6-5
Severity: normal

In /lib/cryptsetup/scripts/decrypt_ssl the relevant decryption command,
    /usr/bin/openssl enc -aes-256-cbc -d -salt -in $1 >/dev/null 2>&1
redirects output from openssl enc -d to /dev/null, rendering the script
useless except for checking the key can actually be decrypted.  I'm not sure
that was the intent.

Best regards,
	g.
