Instance methods

hash(input : String, output_size : Int32, raw_output : Bool = false) : String

Returns Keccak (not the standardized SHA3) of the given string.

Parameters

  • input - Input string.
  • output_size - Size of returning hash in bits.
  • raw_output - if false returns hex-encoded string, raw bytes otherwise.

Returns String - The SHA3 result of the given string.

Source
hash(input : Bytes, output_size : Int32) : Bytes

Returns Keccak (not the standardized SHA3) of the given string.

Parameters

  • input - Input bytes.
  • output_size - Size of returning hash in bits.

Returns Bytes - The SHA3 result of the given string.
