1 Specification

  • digest size: 160 bits
  • max. message length: < 264 bits
  • compression function: 512-bit message block, 160-bit chaining variable
  • Specification: FIPS 180-2 Secure Hash Standard

2 Cryptanalysis

2.1 Best Known Results

The best collision attack on full SHA-1 was published by Wang et al. It has complexity of 269 hash evaluations. The best collision example, a 70-step collision for SHA-1, was published by DeCanniere, Mendel and Rechberger.
