Hexadecimal password

If you were given a password that uses only the hexadecimal range of characters (which are: abcdef0123456789), add a dollar sign ($) before the password. These passwords are at least 10 characters long for 40-bit encrypted networks or at least 26 characters long for 128-bit encrypted networks.

Note: In a hexadecimal password, the dollar sign is called the Hex Escape. It notifies the software that the characters that follow it should be treated as a hexadecimal number. Other possible hex escapes are "0x" and "0X" (zero-x, and the "x" may be upper or lower case).

Example of 40-bit: $1234abcdef

Example of 128-bit: $12345678901234567890abcdef
