package eqaf-cstruct

v0.10 2024-06-14 Kyoto (Japon)

• Implement functions provided by eqaf on bytes (@FantomeBeignet, #41)
• Choose the right clock on MSVC systems (@dra27, #40)
• Fix the lower bounds about base64 (@hannesm, #45)
• Split eqaf and eqaf-cstruct (@dinosaure, @hannesm, #43)

v0.9 2022-07-24 Paris (France)

• Add support of OCaml 5.00 (@kit-ty-kate, #37)
• Add support for current-bench and fix bad r² for unequal strings (@Zined-Ada, @art-w, #38)
• Add benchmark with bechamel (@Zineb-Ada, @art-w, #38)

v0.8 2021-08-06 Paris (France)

• Fix the check tool on 4.11.0 (@dinosaure, @cfcs, @stedolan, #30) The compilation on 4.11 triggers a case where the locality of the expected value when we test exists_uint8 must be the same. Otherwise, the access to this value can have a cost which faults our result.

• Add several utility functions (@cfcs, @dinosaure, #26)

  • bytes_of_hex & string_of_hex, hex decoding
  • hex_of_bytes & hex_of_string, hex encoding
  • divmod, unsigned int32 division with small divisors
  • ascii_of_int32, conversion from int32 to decimal string representation
  • lowercase_ascii & uppercase_ascii, constant-time implementation of String.{lower,upper}case_ascii
  • select_a_if_in_range, like select_int but only supporting positive ranges
  • int_of_bool & bool_of_int, constant-time of Bool.to_int

  A documentation exists for each function. The constant-time is checked only systematically for divmod.

• Merge optional sub-packages (@kit-ty-kate, @hannesm, @dinosaure, #27) cstruct becomes a required dependency of eqaf
• Fix FreeBSD support and remove support of < OCaml 4.07 and remove the dependency to bigarray-compat (@hannesm, @dinosaure, #32)
• Add a CI on FreeBSD (@dinosaure, @hannesm, #33)
• Remove the test check/check.exe (@dinosaure, #31) The test check/check.exe is really volatile and should be executed into a controlled environment (for instance, with nice -n19 and a bare-metal computer). We still require the test for any improvement of eqaf but it is executed separately from our CI.

v0.7 2020-04-16 Paris (France)

• Add find_uint8 (@dinosaure, @cfcs, #20)
• Add exists_uint8 (@dinosaure, @cfcs, #20)

v0.6 2020-03-11 Paris (France)

• remove build dependency on dune (@CraigFe, #16)
• add bigarray-compat and optional dependencies (@hannesm, #17)
• add select_int, one_if_not_zero, zero_if_not_zero (@cfcs, @dinosaure, #19, #18)

v0.5 2019-07-01 Paris (France)

• Delete min and use <> operator to compare length on equal function
• Implementation of compare_{be,le}{,with_len} function (@cfcs, @hannesm, @dinosaure)
• Test on compare function (@dinosaure)
• Unit test on compare (@dinosaure)
• Fuzz test on compare (@dinosaure)
• Documentation (@dinosaure, @cfcs)

v0.4 2019-05-24 Paris (France)

• Distribution integrate an attack example
• Fuzzer to test equal function
• Unroll internal loop over 16 bits integers instead 32 bits
• Put x86 ASM output in implementation (and audit)
• Do second check even if first on fails (bad r²)
• Avoid indirection to Pervasives functions

v0.3 2019-05-02 Paris (France)

• Provide Eqaf_bigstring
• Provide Eqaf_cstruct
• New check tool and delete any dependencies on eqaf package (@dinosaure, @hannesm, @cfcs)

NOTE: This version is buggy, you MUST use v0.2 or v0.4

• Dunify project
• Update OPAM file
• Avoid core_bench dependency
• Make benchmark to test constant-time on eqml
