gabridome a0abffd38c Mac os adjustments 
Mac Os 10.11 protects the files with a set up called SIP that must be disabled 
to be able to modify the .plist file.
Also provided the path for the file in 10.2 MAC OSX systems.
Still the "keytocard" operation doesn't work but the card is visible with
gpg2 --card-status and is editable with gpg2 --card-edit command.

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 is in beta stage with known missing parts (see also Add-on) :

  • Ledger Blue support
  • Seed mode ON/OFF via apdu

Installation

NanoS

From source

  • use at least the Nano S SDK 1.3.1.4 on firmware 1.3.1
  • replace lib_stusb/STM32_USB_Device_Library/Class/CCID/src/usbd_ccid_if.c by the one provided in sdk/ directory

From Binary

Use the Chrome App "Ledger Manager". See https://www.ledgerwallet.com/apps/manager for details.

As "OpenPGP card" application is not fully released, click on "Show delevoppers items" on the bottom right corner.

Host

Linux

You have to have to add the NanoS to /etc/libccid_Info.plist

In  <key>ifdVendorID</key>      add the entry  <string>0x2C97</string>
In  <key>ifdProductID</key>     add the entry  <string>0x0001</string>
In  <key>ifdFriendlyName</key>  add the entry  <string>Ledger Token</string>

This 3 entries must be added at the end of each list.

MAC

  1. First it is necessary to disable SIP That doesn't allow the editing of files in /usr/.

  2. You have to have to add the NanoS to /usr/libexec/SmartCardServices/drivers/ifd-ccid.bundle/Contents/Info.plist

    In  <key>ifdVendorID</key>      add the entry  <string>0x2C97</string>
In  <key>ifdProductID</key>     add the entry  <string>0x0001</string>
In  <key>ifdFriendlyName</key>  add the entry  <string>Ledger Token</string>

This 3 entries must be added at the end of each list.

  1. Enable SIP

Windows

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 in doc/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.
