Computes bytes digest using SHA-1 algorithm. Computes bytes digest using US Secure Hash Algorithm 1 (SHA-1).

Fields

• char _chars[20]
• unsigned char _bytes[20]
• u32 _digest[5]
• u64 _dwords[8]
• u32 _words[80]
• unsigned char _block[64]

Methods

• digest_bytes_length() -> constexpr int

  Returns 20.

• digest_length() -> constexpr int

  Returns 5.

• length() const -> std::size_t

  Get the length of SHA1 input in bits.

• digest_chars() const -> const char *

  Get SHA-1 digest as a pointer to character array.

• digest_bytes() const -> const unsigned char *

  Get SHA-1 digest as a pointer to unsigned byte array.

• digest() const -> const u32 *

  Get SHA-1 digest as a pointer to unsigned integer array.

• digest(u32 * result) -> void

  Copy SHA-1 digest to unsigned integer array pointed by result.

• digest(char * result) -> void

  Copy SHA-1 digest to character array pointed by result.

• digest(unsigned char * result) -> void

  Copy SHA-1 digest to byte array pointed by result.

• compute() -> void

  Compute the final digest by padding the last block if needed. If the block does not require padding this method does nothing.

• put(const char * first, const char * last) -> void

  Append next byte array between first and last and compute digest if possible.

  std::length_error

  if input size is too large to compute SHA-1 on this system

  
  

• put(const char * first, std::size_t n) -> void

  Append next n bytes from array pointed by first and compute digest if possible.

  std::length_error

  if input size is too large to compute SHA-1 on this system

  
  

• reset() -> void

  Reset SHA-1 object to start computing new hash.

• sha1()

  Construct SHA-1 digest object.
