invalid tag error cannot be caught?

[jdutchak]

updated from 0.1.4 to 0.4.0 now i keep getting invalid tag error - has something changed here? what should I look for?

Error: invalid tag
at Object.decrypt (node_modules/@noble/ciphers/src/chacha.ts:266:48)

any specific test vector you could share?

[jdutchak]

gives hard error that some apps cannot recover from ie Preact with ViteJS and Electron --- vs just wrong or invalid tag error depending on lib ver 0.1.4 or 0.4.0

const d =  XChaCha20Poly1305.decrypt({
              data  : new Uint8Array(10),
              key   : new Uint8Array(32),
              nonce : new Uint8Array(24),
              tag   : new Uint8Array(16)
            })
console.log(d)

Works fine for me with 0.4.0, the error is correctly catched:

import { xchacha20poly1305 } from '@noble/ciphers/chacha';
const key = new Uint8Array(32);
const nonce = new Uint8Array(24);
const chacha = xchacha20poly1305(key, nonce);
try {
  const data_ = chacha.decrypt(new Uint8Array(32));
} catch (error) {
  // console.log('log', error)
}

do you not need to pass a tag in 0.4.0 ?

[paulmillr]

huh? it was never needed, not even in 0.1.4
