Encryption/Decrption

Create public/private key

In order to initially generate the public/private keys, use the bundles shell script create-keypair.sh. This creates a 2048bit pair as follows:

openssl req -x509 -nodes -newkey rsa:2048 \
	-keyout mysqldump-secure.priv.pem \
	-out mysqldump-secure.pub.pem

You can test the performance on your target machine yourself with:

openssl speed rsa512

Values on my machine are

	rsa 512	rsa 1024	rsa 2048	rsa 4096
# of sign/s	6,878.4	2,075.8	398.8	66.4
# of verify/s	99,898.4	42,966.3	15,396.4	4,751.5
