Last week:

• libgcrypt
  • Clean up existing code to be friendly for ECC_DIALECT_SAFECURVE
    • Use "/q" for public key and secret key, handle point representation as an opaque bytes
    • Use "/e" for ephemeral key, handle point representation as an opaque bytes
    • Use unsigned integer for cofacter (not MPI)
    • Use mpi_ec_t to remove ECC_public_key and ECC_secret_key
      • Once, it attempted to have an abstraction of mpi_ec_t only in libgcrypt/mpi (not publishing internal to libgcrypt/cipher), but now ec-context.h is used in libgcrypt/cipher. It didn't work as originally written in the past.
    • more clean up of ECC.
  • Introduce new practice with new dialect of ECC_DIALECT_SAFECURVE
    • Native to the Curve algorithm
      • fixed-size, little-endian for
        • Point representation
        • binary of secret
        • integer in "s" in signature (in future)
  • Define X448 using ECC_DIALECT_SAFECURVE
• GD32VF103
  • Got the board and write LED blinking using kp's gcc-riscv64-unknown-elf package in Debian.
  • It found that USB peripheral is different. At start, it runs from 0x00000000 need to jump to 0x08000000.
  • BOOT0/BOOT1 setup enables DFU mode at boot from USB: we can use dfu-util in Debian.

This week:

• OpenPGP
  • Examine the standard. What needed is introducing native bytes instead of MPI which has integer semantics
    • Say, I say "Simply, Opaque String" (SOS) for now, to be replaced by more relevant term
    • Just like MPI which has two-octet scalar for its bit-size and octet string, but no assumption it's big-endian.
    • Bit-size is normally 8*(sizeof octet string), but it is also OK (for backward compatibility) bit-size%8 != 0 (0x40 prefix for EdDSA/Curve25519 point representation).
    • For point representation, secret, and integer in signature
• GnuPG
  • Investigate how to introduce handling of SOS
• libgcrypt
  • Test master for GNUnet.

Last week:

• Vacation

This week:

• GnuPG 2.2.18

Last week:

• Sick leave

This week:

• Add GUI for self signature annotations and filtering on them to Kleopatra.
• Some GpgOL work.
• Put together an installer with these changes.
