About this app
sub rosa by naiveHA Uncomplicatedly simple: if you manage your long, complex, and secure passwords in a password manager app (like KeePassDroid) on your Android device, you can now “type” them easily, in public, without worrying about surveillance cameras or shoulder surfing, on any other device—phone, tablet, or PC—running Windows, Linux, or macOS.
sub rosa allows you to program the static password on your YubiKey, so you can “type” the password with the touch of a finger. When you’re done “typing” your long, complex, and secure password, be sure to wipe your YubiKey clean. It isn’t much security if someone else can “type” your password by touching the YubiKey.
The various keyboards accept the following characters:
US: space, \n, \t and abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!"#$%&'`()*+-=,./:;<>?@\][^_{}|~
UK: space, \n, \t and abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@£$%&'`()*+-=,./:;<>?"#][^_{}~¬
DE: space, \n, \t and abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!"#$%&'()*+-=,./:;<>?^_`§´ÄÖÜßäöü
FR: space, \n, \t and abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!"$%&'()*+-=,./:;<_£§°²µàçèéù
IT: space, \n, \t and abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!"#$%&'()*+,-./:;<=>?@^_`|£§°çèéàìòù
MODHEX: bcdefghijklnrtuvBCDEFGHIJKLNRTUV
Since version 2.0.0, sub rosa has added support for OpenPGP. You can now provision an OpenPGP key onto your YubiKey, Nitrokey 3, Nitrokey Pro or Librem Key. In keeping with the app’s motto, “Uncomplicatedly simple,” you can encrypt, decrypt, sign, and authenticate with your security key, then wipe it clean and write another OpenPGP key to change your digital identity. SSH authentication is simpler now—you no longer need to reuse the same SSH key or buy multiple security keys
