Michael, I would consider using zEDC which can be called by authorized and non-authorized programs in z/OS, and C and JAVA.
It’s very fast, and requires zEC12 GA2, zBC12, z13 or later. You must have certain PTFs applied. z15 and later machines have it built in. This is a standard format and can be used on non-IBM systems. If applicable, you can do it without program changes using DATACLAS.
