  • _mm_sha1msg1_epu32⚠sha
    Performs an intermediate calculation for the next four SHA1 message values (unsigned 32-bit integers) using previous message values from a and b, and returning the result.
  • _mm_sha1msg2_epu32⚠sha
    Performs the final calculation for the next four SHA1 message values (unsigned 32-bit integers) using the intermediate result in a and the previous message values in b, and returns the result.
  • _mm_sha1nexte_epu32⚠sha
    Calculate SHA1 state variable E after four rounds of operation from the current SHA1 state variable a, add that value to the scheduled values (unsigned 32-bit integers) in b, and returns the result.
  • _mm_sha1rnds4_epu32⚠sha
    Performs four rounds of SHA1 operation using an initial SHA1 state (A,B,C,D) from a and some pre-computed sum of the next 4 round message values (unsigned 32-bit integers), and state variable E from b, and return the updated SHA1 state (A,B,C,D). FUNC contains the logic functions and round constants.
  • _mm_sha256msg1_epu32⚠sha
    Performs an intermediate calculation for the next four SHA256 message values (unsigned 32-bit integers) using previous message values from a and b, and return the result.
  • _mm_sha256msg2_epu32⚠sha
    Performs the final calculation for the next four SHA256 message values (unsigned 32-bit integers) using previous message values from a and b, and return the result.
  • _mm_sha256rnds2_epu32⚠sha
    Performs 2 rounds of SHA256 operation using an initial SHA256 state (C,D,G,H) from a, an initial SHA256 state (A,B,E,F) from b, and a pre-computed sum of the next 2 round message values (unsigned 32-bit integers) and the corresponding round constants from k, and store the updated SHA256 state (A,B,E,F) in dst.
