.SH "HOW TO CREATE ENCRYPTION KEYS FOR AMCRYPT"
-
-1\&. Create 65 random encryption keys and encrypt those keys using gpg\&. Reading
-from /dev/random may take indefinitely long if kernel's random entropy pool
-is empty\&. If that happens, do some other work on some other console (use
-keyboard, mouse and disks)\&.
-
.PP
-head \-c 2925 /dev/random | uuencode \-m \- | head \-n 66 | tail \-n 65 \\ | gpg \-\-symmetric \-a > ~amanda/\&.gnupg/am_key\&.gpg

.PP
This will ask for a passphrase\&. Remember this passphrase as you will need it in the next step\&.

.PP
2\&. Store the passphrase inside the home\-directory of the AMANDA\-user and protect it with proper permissions:
.nf
-
echo my_secret_passphrase > ~amanda/\&.am_passphrase
chown amanda:disk ~amanda/\&.am_passphrase
chmod 700 ~amanda/\&.am_passphrase
.fi

.SH "KEY AND PASSPHRASE"
-
.PP
- \fBamcrypt\fR uses the same key to encrypt and decrypt data\&.
-
-It is very important to store and protect the key and the passphrase
-properly\&. Encrypted backup data can \fBonly\fR be recovered with the correct key and
-passphrase\&.
