According to the [NodeJS CCM example](https://nodejs.org/docs/latest-v14.x/api/crypto.html#crypto_ccm_mode], when decrypting the `plaintextLength` parameter actually refers to the ciphertext length, not the plaintext length: ``` decipher.setAAD(aad, { plaintextLength: ciphertext.length }); ``` The same can be seen in the [OpenSSL docs](https://wiki.openssl.org/index.php/EVP_Authenticated_Encryption_and_Decryption) where a call to `EVP_DecryptUpdate` passes the ciphertext length: ``` /* Provide the total ciphertext length */ if(1 != EVP_DecryptUpdate(ctx, NULL, &len, NULL, ciphertext_len)) handleErrors(); ``` This parameter probably should have been called `inputLength` or `bufferLength` instead of `plaintextLength`, so that it makes sense both when encrypting and decrypting, but at least we can correct the sentence in the documentation for now to refer to the correct value.
