- * Length of Q specified by N. If zero, The PKCS #11 module will

- * The underlying PKCS #11 module will check the values for L, N,

- * If L <= 1024, then L must be between 512 and 1024 in increments of 64 bits.
- * If L <= 1024, then N must be 0 or 160.
- * If L >= 1024, then L and N must match the following table:
- *   L=1024   N=0 or 160
- *   L=2048   N=0 or 224
- *   L=2048   N=256
- *   L=3072   N=0 or 256
