GnuPG application: blue-app-gnupg
GnuPG application for Ledger Blue and Nano S
This application implements "The OpenPGP card" specification revision 3.0. This specification is available in doc directory and at https://g10code.com/p-card.html .
The application supports:
- RSA with key up to 4096 bits
- ECDSA with secp256k1, secp256r1, brainpool 256r1 and brainpool 256t1 curves
- EDDSA with Ed25519 curve
- ECDH with secp256k1, secp256r1, brainpool 256r1, brainpool 256t1 and curve25519 curves
This release has known missing parts (see also Add-on) :
- Ledger Blue support
- Seed mode ON/OFF via apdu
Installation and Usage
See the full doc at https://github.com/LedgerHQ/blue-app-openpgp-card/blob/master/doc/user/blue-app-openpgp-card.pdf
Add-on
The GnuPG application implements the following addon:
- serial modification
- on screen reset
- 3 independent key slots
- seeded key generation
Technical specification is available at https://github.com/LedgerHQ/blue-app-openpgp-card/blob/master/doc/developper/gpgcard3.0-addon.rst
Key slot
"The OpenPGP card" specification specifies:
- 3 asymmetric keys : Signature, Decryption, Authentication
- 1 symmetric key
The blue application allow you to store 3 different key sets, named slot. Each slot contains the above 4 keys. You can choose the active slot on the main screen. When installed the default slot is "1". You can change it in settings.
seeded key generation
A seeded mode is implemented in order to restore private keys on a new token. In this mode key material is generated from the global token seeded.
Please consider SEED mode as experimental.
More details to come...
On screen reset
The application can be reset as if it was fresh installed. In settings, choose reset and confirm.
