Here're the bare basics for ILE RPG and CIPHER:

 D PlainText       S               *
 D CipherText      S               *
 D Controls        DS            32
 D   Function                     5I 0
 D*  Length                       5I 0 inz(%size(Input))
 D   Length                       5I 0 inz( 64 )
 D   CBC_Mode                     1A   inz(X'40')
 D   SecretKey                    1A   dim(8)
 D   Reserved_1                   1A   inz(*loval)
 D   InitChain                    8A   inz(X'5555555555555555')
 D   Reserved_2                  10A   inz(*loval)

 C                   eval      PlainText  = %addr( Input )
 C                   eval      CipherText = %addr( Output )

 C                   callb     '_CIPHER'
 C                   parm                    CipherText
 C                   parm                    Controls
 C                   parm                    PlainText

For details, check the CIPHER documentation. Modify as needed, etc. For basic 
stuff, that's about all there is to it.
