Generates a pseudorandom (rather than a truly random)
series of bytes to use as an encryption key, and returns the key
as a RAW value.
Notes
- You
are responsible for generating, storing, and transporting this value.
- The size of the generated encryption key is determined by the
cryptographic algorithm specified by the SYMMETRIC-ENCRYPTION-ALGORITHM
attribute.
- The Alternate Random Number Generator (-rand)
startup parameter setting has no effect on this function.
