Looks up the correct ASN1 OID of the passed in algorithm string and returns the encryptor. The encryption key length is set where necessary

Parameters:

algorithm - The name of the algorithm to use for encryption

Returns:

the OutputEncryptor of the given hash algorithm

Throws:

NoSuchAlgorithmException - - Houston we have a problem TODO: Possibly just use new ASN1ObjectIdentifier(algorithm) instead of explicit lookup to support random configured algorithms but will require determining if this has any side effects from a security point of view.
