Common base class for all derived SHA1 implementations.

See Also: SHA1 Members

Syntax

[System.Runtime.InteropServices.ComVisible(true)]
public abstract class SHA1 : HashAlgorithm

Remarks

Recent attacks on the SHA-1 algorithm suggest that it can be broken with a complexity of about 2^63, while a normal brute-force attack would be 2^80. You are encourage to migrate your applications to larger version of SHA.
