Summary

Provides a low-level interface to the crypto/subtle package.

Package subtle implements functions that are often useful in cryptographic
code but require careful thought to use correctly.

Constants

Constants are variables with :const true in their metadata. Joker currently does not recognize them as special; as such, it allows redefining them or their values.

Functions, Macros, and Special Forms

• ConstantTimeByteEq

  Function v1.0

  (ConstantTimeByteEq x y)
  

  ConstantTimeByteEq returns 1 if x == y and 0 otherwise.
  
  Go input arguments: (x uint8, y uint8)
  
  Go returns: int
  
  Joker input arguments: [^Int x, ^Int y]
  
  Joker returns: ^Int

• ConstantTimeCompare

  Function v1.0

  (ConstantTimeCompare x y)
  

  ConstantTimeCompare returns 1 if the two slices, x and y, have equal contents
  and 0 otherwise. The time taken is a function of the length of the slices and
  is independent of the contents. If the lengths of x and y do not match it
  returns 0 immediately.
  
  Go input arguments: (x []byte, y []byte)
  
  Go returns: int
  
  Joker input arguments: [^arrayOfByte x, ^arrayOfByte y]
  
  Joker returns: ^Int

• ConstantTimeCopy

  Function v1.0

  (ConstantTimeCopy v x y)
  

  ConstantTimeCopy copies the contents of y into x (a slice of equal length)
  if v == 1. If v == 0, x is left unchanged. Its behavior is undefined if v
  takes any other value.
  
  Go input arguments: (v int, x []byte, y []byte)
  
  Joker input arguments: [^Int v, ^arrayOfByte x, ^arrayOfByte y]

• ConstantTimeEq

  Function v1.0

  (ConstantTimeEq x y)
  

  ConstantTimeEq returns 1 if x == y and 0 otherwise.
  
  Go input arguments: (x int32, y int32)
  
  Go returns: int
  
  Joker input arguments: [^Int x, ^Int y]
  
  Joker returns: ^Int

• ConstantTimeLessOrEq

  Function v1.0

  (ConstantTimeLessOrEq x y)
  

  ConstantTimeLessOrEq returns 1 if x <= y and 0 otherwise.
  Its behavior is undefined if x or y are negative or > 2**31 - 1.
  
  Go input arguments: (x int, y int)
  
  Go returns: int
  
  Joker input arguments: [^Int x, ^Int y]
  
  Joker returns: ^Int

• ConstantTimeSelect

  Function v1.0

  (ConstantTimeSelect v x y)
  

  ConstantTimeSelect returns x if v == 1 and y if v == 0.
  Its behavior is undefined if v takes any other value.
  
  Go input arguments: (v int, x int, y int)
  
  Go returns: int
  
  Joker input arguments: [^Int v, ^Int x, ^Int y]
  
  Joker returns: ^Int
