Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

Digest::HMAC - Keyed-Hashing for Message Authentication
# Functional style use Digest::HMAC qw(hmac hmac_hex); $digest = hmac($data, $key, \&myhash); print hmac_hex($data, $key, \&myhash); # OO style use Digest::HMAC; $hmac = Digest::HMAC->new($key, "Digest::MyHash"); $hmac->add($data); $hmac->addfile(*FILE); $digest = $hmac->digest; $digest = $hmac->hexdigest; $digest = $hmac->b64digest;
HMAC is used for message integrity checks between two parties that share a secret key, and works in combination with some other Digest algorithm, usually MD5 or SHA-1. The HMAC mechanism is described in RFC 2104. HMAC follow the common "Digest::" interface, but the constructor takes the secret key and the name of some other simple "Digest::" as argu- ment.
