What encryption format is used in Mapper's Encrypt and Decrypt logic?

Question

I want to encrypt data by specifying an encryption format, MD5 for example.
What encryption format is used in Mapper's Encrypt and Decrypt logics?

Answer

Mapper's Encrypt and Decrypt logics use HULFT Square's own encryption method.
The method's details are not disclosed because that information may lead to deciphering encrypted data.

If you need to specify encryption format, please consider using an encryption web service by the REST connector.
