As Toma┼ż said, it may depend on what you're actually up to..
Likely you do not want to use the CryptTool Encrypt/Decrypt wrappers
directly.

If it is for OOXML encryption there are two engines derived from
CryptoEngine of include/oox/crypto/CryptoEngine.hxx, AgileEngine of
include/oox/crypto/AgileEngine.hxx and the older Standard2007Engine of
include/oox/crypto/Standard2007Engine.hxx

The engines provide a generateEncryptionKey() function, which is called
by an engine's setupEncryption(const OUString& rPassword) after presets
have been initialized, for usage see for example
oox/qa/unit/CryptoTest.cxx
