NAME¶
strrot13 - encrypt or decrypt string using rot13
SYNOPSIS¶
#include <publib.h>
char * strrot13(char *str);
DESCRIPTION¶
strrot13 converts the argument string using rot13, i.e., it replaces each
letter a with n, n with a, b with o, o with b, and so on. Converting twice
results in the original string. Non-letter characters are not converted.
The rot13 encryption method is used commonly on USENET to hide offensive text,
or spoilers in discussions about movies or books, or in other similar
occasions.
RETURN VALUE¶
strrot13 returns its argument.
