jotpass — Print + readable random passwords

+
+
+

+ + + + + +
jotpass[-v] [-a + alphabet] [-g + groups] [-w + width] [-s + separator]
+
+
+

+

The jotpass utility facilitates generating + random passwords suitable for handwriting.

+

The options are as follows:

+
+
+
Enable verbose mode. Causes jotpass to print the + entropy of the generated password to standard error.
+
+ alphabet
+
Draw characters from the given alphabet. Defaults to + alphanumeric ASCII characters, excluding 01klnuvIO to improve + legibility.
+
+ groups
+
Set the number of groups. Defaults to 12.
+
+ width
+
Set the width of the groups. Defaults to 4 + characters.
+
+ separator
+
Set the group separator character. Defaults to dash + (-).
+
+
+
+

+

The jotpass utility exits 0 on + success, and >0 if an error occurs.

+
+
+

+

Print a random password:

+
+
$ jotpass
+P6ji-4pRZ-Ze7m-q7Bp-Vpye-HCjr-hygF-6TwQ-oRJT-yx6p-SyMB-AwUm
+
+

Specify a custom format:

+
+
$ jotpass -a 0123456789abcdef -g 8 -w 2 -s ' ' -v
+49 1b 6e b0 e2 fc 16 b1
+The generated password has an entropy of 64 bits.
