Answer 1

Well I needed this too recently and I found much easier to take SHA1 implementation from HashLib : http://hashlib.codeplex.com/

Mono implementation have some far-going dependencies (localization of exceptions, etc.), while from HashLib you need only to copy few files without any changes in them:

Converters.cs
Hash.cs
HashBuffer.cs
HashCryptoNotBuildIn.cs
HashResult.cs
IHash.cs
SHA0.cs
SHA1.cs

55 KB of code total, so nothing too heavy.
