But is really recomended to use Whirpool.

Because The SHA is a secure digest algorithm developed by NIST. SHA-1 is a corrected version of the algorithm published in 1994. The algorithm is an ANSI standard. The algorithm takes a message of less than 264 bits and generates a summary of 160 bits. Is slower than MD5, but most key length makes it more resistant to attack by brute-force collision and investment.

Now exists SHA512 function works in a message block of 1024 bits and an intermediate hash value of 512 bits. It is essentially a block cipher that encrypts 512-bit intermediate value using the block as a key message.

The sha hash is cracked now, with a C# code Allow the choice of encryption algorithm using a list.
The resistance of SHA-1 algorithm has been compromised during the year 2005

Please upgrade SHA1 to SHA2 (Uses 512 bits).
