A packed or zoned decimal field can be used as input to encryption 
routines. You can simply pass a pointer to the field, just as you would 
with a character field.

However, you can't store the encrypted result in a packed/zoned field 
because the encrypted data may not be a valid number in packed/zoned 
format.

Also, keep in mind that the encrypted field could be longer than the 
input, depending on the encryption alogrithm. So you'll want a character 
field that's a bit longer to store the results in.

Hope that helps...
