Functions

cmov(Uint8List r, Uint8List x, int len, int b) → void

Copies the contents of x to r if b is 1, otherwise does nothing. The operation is performed in constant time, without its time varying depending on the data, only on the length.

verify(Uint8List a, Uint8List b) → bool

Compares two byte arrays a and b in constant time. Returns true if they are identical, false otherwise. This function avoids early exits that could leak information.
