looking for an alternative. FreeBSD for example recommends "security/makepasswd", which is written in Perl
|
||||
but requires a lot of dependency packages and doesn't offer the feature-set/flexibility of APG.

Since FIPS-181 (pronouncable passwords) has been withdrawn in 2015, I didn't see any use in replicating that

feature. Therfore apg-go does not support pronouncable passwords.
|
||||
Since FIPS-181 (pronouncable passwords) has been withdrawn in 2015, apg-go does not follow this standard. Instead
|
||||
it implements the [Koremutake Syllables System](https://shorl.com/koremutake.php) in its pronouncable password mode.

### Pronouncable passwords
|
||||
Since v0.4.0 apg-go supports pronouncable passwords, anologous to the original c-apg using the `-a 0`
|
||||
flag. The original c-apg implemented FIPS-181, which was withdrawn in 2015 for generating pronouncable
|
||||
passwords. Since the standard is not recommended anymore, `apg-go` instead make use of the
|
||||
[Koremutake Syllables System](https://shorl.com/koremutake.php). Similar to the original apg, `agp-go`
|
||||
will automatically randomly add special characters and number (from the human-readable pool) to each
|
||||
generated pronouncable password. Additionally it will perform a "coinflip" for each Koremutake syllable
|
||||
and decided if it should switch the case of one of the characters to an upper-case character.
|
||||
|
||||
Using the `-t` parameter, `apg-go` will display a spelled out version of the pronouncable password, where
|
||||
each syllable or number/special character is seperated with a "-" (dash) and if the syllable is not a
|
||||
Koremutake syllable the character will be spelled out the same was as with activated `-l` in the
|
||||
non-pronouncable password mode (`-a 1`).
|
||||
|
||||
**Note on password length**: The `-m` and `-x` parameters will work in prouncable password mode, but
|
||||
please keep in mind, that due to the nature how syllables work, your generated password might exceed
|
||||
the desired length by one complete (which can be up to 3 characters long).
|
||||
|
||||
**Security consideration:** Please keep in mind, that pronouncable passwords are less secure then truly
|
||||
randomly created passwords, due to the nature how syllables work. As a rule of thumb, it is recommended
|
||||
to multiply the length of your generated pronouncable passwords by at least 1.5 times, compared to truly
|
||||
randomly generated passwords. It might also be helpful to run the pronoucable password mode with enabled
|
||||
"HIBP" flag, so that each generated password is automatically checked against "Have I Been Pwned"
|
||||
database.
