Can anyone explain how this string has likely been encrypted at all?
AES256:29://(Hex://5B18C3AD8CFR4D38)
I’ve never seen an encryption has like this before in my life. Would it be possible to replicate with PHP? (Providing I can get what salts etc may have been used etc).
This is for a migration of data from one website to another – currently this data is stored in a MSSQL DB but will be used in MySQL if PHP can handle the encryption.
It appears to be part of a 256bit hash with some metadata around it. I’m not familiar with the php libraries for encryption but know that you can create a 256bit sha with php and there should be a toHex() method.
To check a password, encrypt the users entry with sha256 and check its hex value against the one stored. Have you checked to see if its the first 1/4 of a sha? Maybe they just truncate for lack of security?
If I had the guess, the 29 is probably userid, but could be a salt or something.
