to generate a gpg key, run the following:

gpg --gen-key

when that completes, run

$ gpg --list-keys cjcollier@mysql.com
pub 1024D/6CC27EA8 2001-04-27
uid C.J. Collier
uid C.J. Collier
uid C.J. Collier

After you generate it, you should publish your public key:

gpg --keyserver pgp.mit.edu --send-keys

mine looks like this:

$ gpg --keyserver pgp.mit.edu --send-keys 6CC27EA8
gpg: sending key 6CC27EA8 to hkp server pgp.mit.edu

You can get my GnuPG key with the following command:

$ gpg --keyserver pgp.mit.edu --recv-keys 6CC27EA8

Let me know what your ID is when you complete this. When I see you
next, I'll sign your …

Review/baseline:

For current versions of MySQL, permissions are granted and revoked by the GRANT and REVOKE commands. In older versions, administrators had to muck with the access control tables by hand, and then FLUSH PRIVILEGES to enable the new access controls.

The blog entry got me thinking. Currently, if you want to remove all rights from a user, including the ability to login, you have to REVOKE privileges and then DELETE from the mysql.user table. And then, of course, FLUSH PRIVILEGES because you manually …

With some inspiration from Ben Ramsey i created a little demo for using my md5 database during the signup process on a website.

This example demonstrates the use of the MD5 database at http://md5.rednoize.com and AJAX to check password strength during signup on a website. After supplying a username and a password, a md5 hash of the password is generated using Paul Johnston's md5 javascript library.

The hash of the password (not the password itself) is then sent to http://md5.rednoize.com. If the website returns a result for the given password (hence the hash password combination is stored in the md5 database) it can be regarded as …
