Recent Releases of scicrypt

scicrypt - v0.7.1

  • Fixes bug in docs of scicrypt-bigint that caused it to crash on docs.rs
  • Equality checking is now done in constant-time and is correct regardless if the number of limbs differs between the operands
  • Comparisons are now correct but run in variable-time. A convenient way of comparing a and b is a.leak() < b.leak(). In other words, leaky overloaded operators are supported after calling leak() on an UnsignedInteger. Otherwise, all overloaded operators run in constant-time.
  • Implemented Hash for UnsignedIntegers
  • Implemented div_rem (constant-time) for UnsignedIntegers. The div operation simply calls this function and 'forgets' the remainder.
  • Implemented reduce_leaky, which cuts away all leading zero-limbs from an UnsignedInteger. This fixes a bug when exporting to rug's integers.
  • Implemented Send for UnsignedInteger

scicrypt - v0.7.0

  • New crate: scicrypt-bigint. These BigIntegers internally use GMP's constant-time functions.
  • The whole library now uses scicrypt-bigint
  • Split encryption into encrypt_without_randomness and randomize

scicrypt - v0.6.1

  • Implements Serde for several cryptosystems
  • Implements ciphertext subtraction, constant addition and constant subtraction for additively homomorphic cryptosystems
  • Implements a decrypt-to-identity operation (which is faster for some cryptosystems than decryption and checking for identity)

scicrypt - v0.6.0

  • Overhauled the API (for homomorphic encryption)

scicrypt - v0.5.0

  • Order of magnitude faster safe prime generation (comparable to OpenSSL)
  • Provisional traits for secret sharing
