// � EncryptStdBlock()

// Routine Description:

// Takes a block key encrypts the standard text block with it.
// The resulting encrypted block is returned.
// This is a One-Way-Function - the key cannot be recovered from the
// encrypted data block.
//
// Arguments:
//
// BlockKey - The key to use to encrypt the standard text block.
//
// CypherBlock - The encrypted data is returned here
//
// Return Values:
//
// TRUE - The encryption was successful.
// The result is in CypherBlock
//
// FALSE - Something failed. The CypherBlock is undefined.

// password is in LmOwfPassword.
//
// FALSE - Something failed. The LmOwfPassword is undefined.
