At first, grateful all!

I need a reversible routine. I have a table that stores a name (special
user) and a password. This user is responsible sets free several special
resources in my database app. I would like in a trigger, for instance, I
can encrypt the password. Then, I would want decrypt.

Howsoever, the answers are way. Thanks all.

Best regards,

Carlos Arguilar

What are you trying to protect? If you are just trying to hide
passwords so they are not in plain text, then you do not need
encryption, only a hash algorithm like SHA-1 or MD5. Hashing is
simple, because you don't have to manage public and private keys.
There is also no way to "break" a hashing algorithm unless you use a
brute force approach.

Is this what you need, or do you need something that is reversible
into the original string?
