            Crypto Subtle Decrypt Parameter Not Type "CryptoKey"
            Asked 2021-May-19 at 20:30

            I'm trying to decrypt a string using SubtleCrypto that was pre-generated.

            Instead of getting decrypted text I'm getting the error: Failed to execute 'decrypt' on 'SubtleCrypto': parameter 2 is not of type 'CryptoKey'.

            ANSWER

            Answered 2021-May-19 at 20:30

            The parameters have the wrong types: IV and data must be passed as BufferSource, the key as CryptoKey, see SubtleCrypto.decrypt(). A CryptoKey is returned by SubtleCrypto.importKey(), which is used to import the key.

            WebCrypto API (as low level API) does not provide support for data conversion, e.g. Base64 encoded data or strings to BufferSource, so other helper methods must be used for this.

            The following code decrypts the ciphertext:

            openssl requires Hex encoding of manual keys and IVs, not ASCII encoding. (ASCII or UTF-8 encoding these, as the online tools seems to be doing, dramatically reduces your keyspace and makes AES insecure.)

            "E" is 0x45 and "F" is 0x46, so the equivalent openssl command is:

            The website uses neither a padding nor an IV. Therefore in the code the padding must be disabled and the ECB mode must be applied.

            Furthermore the website expects a hex encoded key and ciphertext and returns the decrypted data also hex encoded, which therefore must not be UTF-8 decoded in the code:

            The devlan site explains

            CBC mode is highly recommended and it requires IV to make each message unique. If no IV is entered then default will be used here for CBC mode and that defaults to a zero based byte[16].

            So your prepended IV is considered as a ciphertext block. Now, you have two blocks there. In the CBC mode, the decryption is performed as ( blocks are counted form 1);

            AES encryption without IV in PHP and JS gives different result

            In the PHP code AES-128 is specified. Therefore PHP implicitly truncates the 32 bytes key to the first 16 bytes. In the CryptoJS code only this 16 bytes key may be used.
            Furthermore, key and IV are converted most easily with the CryptoJS encoders into a WordArray.

            Implementing AES/ECB/PKCS5 padding in Python
            Asked 2020-Oct-11 at 16:46

            I am trying to implement a python program to encrypt a plain text using AES/ECB/PKCS5 padding. The output I am getting is slightly different from expected.

            ANSWER

            Answered 2020-Oct-05 at 07:39

            PKCS 5 (or 7) padding is not adding 0 bytes, but adding a c byteswith valuec(where1 <= c <= 16) if you're c` bytes short of a block length multiple.

            So if you already have a multiple of 16, add a full 16 bytes of value 16, and if your last block is 'stop' (4 bytes), we add 12 bytes with value 0xc (12 in hex) to fill up the block. Etc.

            This way the receiver (after decryption of the final block) can check the last byte c and check if the value is 1 <= c <= 16 (if not, reject the decryption) and then check that the last c bytes indeed are all that same value, and then remove them from the decryption. This way the receiver does not have to guess how many bytes of the last block were only padding or really part of the plain text. It's unambiguous doing it the PKCS way.

            I'll leave the coding up to you.
