Here are two ways to solve your
ROT-13 needs.
Use the following
bookmarklet:
javascript:P9 = prompt( 'Text...', '' );
if ( P9 ) {
S2b = '';
for ( J7 = 0; J7 < P9.length; J7++ ) {
C6 = P9.charCodeAt( J7 );
if ( Math.abs( 16 - Math.abs( C6 - 93.5 ) ) <= 13 ) {
W8b = ( C6 < 91 ) ? 65 : 97;
S2b += String.fromCharCode(((C6 - W8b + 13) % 26 ) + W8b);
} else {
S2b += P9.charAt( J7 );
}
}
alert( S2b );
} else {
void ( null );
}
or use the
magical perl y/a-zA-Z/n-za-mN-ZA-M/
