Question: I am just curious if this can be done.

I have the hashed password (algorithm SHA1) and Password salt, would I be able to retrieve the password?

Can it be done in SQL server or can it be done via any software?

example: 

```
 Hashed GQdsHCOcun8JuysvqsM3pP0eeoU=
 Password salt: CDjIsQcbz23NzXZLzHRTVw==

```

Thanks

Answer: 
No. Hashes are one-way functions. You can [brute-force](http://en.wikipedia.org/wiki/Brute-force_attack) the passwords, until you guess the correct password, but you cannot decrypt them.
Short answer is no. SHA1 is a one way hash algorithm. You could theoretically find other words that also produce the same hash (collisions), but it would take a lot of time and computing resources.
