Makekey lets you create a random string of characters for use as encryption key or password.
This string ("key") gets displayed to the screen and (by default) copied to the clipboard.
Current version: 2018-04-10 – download link below.
This program uses the conclip.ew library by Greg Haberek.
makekey [-]length [characterset | - | % | +]
'length' must be a number between 1 and 64.
If 'length' is negative, the key will not be copied to the clipboard.
You can individually specify the set of characters from which the key is created, or choose from four preset options.
either any combination of
a = lower case letters (except l),
A = upper case letters (except I and O),
1 = numbers (except 0),
% = symbols %$-!_
and any other characters, which stand for themselves, e.g. l I O 0 * / ( ) etc.
or one of the following shorthand symbols:
- low security, shorthand for a1, that is, lower case letters (except l) and numbers 1 to 9
% high security, shorthand for aA10%, that is upper ald lower case characters exceot l, I and O, numbers 0 to 9, and symbols %$-!_
+ max security, shorthand for aA10%lIO.+:=*?'(), that is, all upper and lower case letters, numbers 0 to 9, and symbols $%-!_.+:=*?'()
Default is medium security, aA10, that is upper and lower case letters (except l, I and O) plus numbers 0 to 9
makekey -? displays the help text and the program version.
makekey 4 10
length is 4, key created from numbers 0 to 9, e.g. 6007
makekey 6 -
length is 6, key created from lower case letters (except l) and numbers 1 to 9, e.g. nv2ag5
length is 12, key created from upper and lower case letters (except l, I and O) and numbers 0 to 9, e.g. 1z3H8g5sY0ag
