HP C/iX Library Function Descriptions
encrypt
encrypt
Encrypts a block of data.
Syntax
void encrypt (char * block , int edflag );
Parameters
block A pointer to the character array that is encrypted.
edflag An integer that is ignored by the function.
Return Values
None.
Description
The encrypt function scrambles the data in block using the same hashing algorithm used
by crypt(). The encrypt function performs a one-way encryption on the supplied data in
block using an encryption key previously defined to the encryption algorithm using
setkey.
The argument to encrypt is an 8-byte character array. The array is treated as a binary
number. The argument array is modified in place to a similar array representing the bits of
the argument after having been subjected to the hashing algorithm using the key set by
setkey.
