Std.Crypto.digestsMatch

fn

This is a callable function.

What it does

Whether two digests are the same, compared in constant time.

Every word is examined whichever way the answer goes, so how long the

comparison took says nothing about where the two differed. A plain

comparison that stopped at the first difference would say exactly that, and

that is how a secret is guessed one byte at a time.

• Read arrows from left to right: inputs come first, and the final type is returned.
• & borrows a value for this call instead of moving or copying it.
