Generate random octal
This tool produces random octal values, base 8, using only the digits 0 to 7. Octal turns up in file permissions and some low level work. Set how many digits you want and generate one value or a batch, with the decimal value shown alongside.
Octal and decimal together
Each octal value is shown with its decimal equivalent in brackets, so you can read the base 8 string and know the plain quantity at a glance. That pairing is handy when you are cross checking permissions or converting by hand.
Fair and private
Every octal digit is drawn from the browser cryptographic random source. Nothing leaves your device.
