Components

• BER-TLV library
  • Callback-based TLV parsing
  • Builder-based TLV writing
  • Supports 2-byte tags
  • Flexible interface
  • Allocation-free design
• Compact-TLV library
  • Minimalist implementation
  • Can construct historical bytes for ATR
• Fortuna PRNG implementation
  • Well-Known algorithm
  • Refuses operation without seed
• RSA library
  • OAEP encryption
  • MGF1 masking
• String library
  • Character type functions
  • String statistics utility
• Password library
  • Salt and hash

Hacks And Intentions

• ISO filesystem library
  • lots of code exists
  • nothing usable yet
• Authentication library
  • some code exists
  • modularize authentication
  • support key derivation
• TLV object representation
• OATH cipher suite
• Blinding ciphers (pseudonymous buddy matching)
• CBOR implementation
  • we would love to have one
• Codec library
  • hex, base64...
