 The recommendations are fairly consistent.
 
+When using @acronym{GnuTLS} and 
+bit sizes are required as input it is recommended to use the following
+functions:
+@itemize
+
+@item @ref{gnutls_pk_bits_to_sec_param}
+
+@item @ref{gnutls_sec_param_to_pk_bits}
+
+@end itemize
+Those functions will convert a human understandable security parameter
+of @code{gnutls_sec_param_t} type, to a number of bits suitable for a public 
+key algorithm.
