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

Functions ¶
func AnyOverlap ¶
AnyOverlap reports whether x and y share memory at any (not necessarily corresponding) index. The memory beyond the slice length is ignored.
func ConstantTimeCompare ¶
func InexactOverlap ¶
InexactOverlap reports whether x and y share memory at any non-corresponding index. The memory beyond the slice length is ignored. Note that x and y can have different lengths and still not have any inexact overlap.
InexactOverlap can be used to implement the requirements of the crypto/cipher AEAD, Block, BlockMode and Stream interfaces.
func SliceForAppend ¶
SliceForAppend takes a slice and a requested number of bytes. It returns a slice with the contents of the given slice followed by that many bytes and a second slice that aliases into it and contains only the extra bytes. If the original slice has sufficient capacity then no allocation is performed.
