SYNOPSIS
#include <unistd.h>
void encrypt(
char block[64],
int edflag);
PARAMETERS
block Specifies a string containing only bytes with a numerical value of 0 (zero) or 1.
edflag Specifies whether to encrypt or decrypt the block array, as follows:
0 Encrypt the array in place.
1 Decrypt the array in place.
DESCRIPTION
The encrypt( ) function encrypts or decrypts data in conformance with domestic encryption stan-
dards. Programs compiled with this version of the function cannot be exported from the United
States of America.
The character array block is modified in place to become a similar array. The basis of the
modification is a key previously specified by a call to the setkey( ) function.
NOTES
The encrypt( ) function can be called only by native processes.
RETURN VALUES
The encrypt( ) function does not return a value. If the call fails, the encrypt( ) function returns a
null pointer.
ERRORS
The HP implementation of encrypt( ) does not set errno.
RELATED INFORMATION
Functions: crypt(3), setkey(3).
STANDARDS CONFORMANCE
The HP implementation of this function does not return errno values.
