[TYPO3-english] migration from old fe_users with md5 passwords to rsaauth and saltedpasswords

[Ansgar B.]

Hi all,

does anybody thought about a migration from old FE User passwords to new 
rsaauth-based passwords?

In concrete situation I have old passwords stored as md5 hashes in DB 
and want to migrate to rsaauth and salted passwords.

Are there any hook where I can
1. fetch the password
2. build a md5 hash
3. check it againt old password
4. build new password
5. write it to the database


Regards

Ansgar
