WebFirst, if the decompressed input size is not a whole number of bytes, 0 bits are padded to the most significant bit side till the next byte boundary. Next, if the output element size is larger than the byte padded input element, bytes of value 0 are added based on the Padding Direction bit in the CCB. WebThe low byte of the system variable @platform% identifies the system on which a program is running. For any of the Pico builds this will have the value 6. If running on a standard Pico, the other three bytes will be zero. If running on a Pico W, the second byte (bits 8-15) will have one of the following values:

However, if the decryption is wrong for some reason (e.g. incorrect key), there is a significant chance you end up still with a valid padding. Also padding is problematic with timing attacks. bisbas hardware albert park

The "unpad" call happens after the decrypt call, and the input to decrypt is the padded bytes from the base-64 encoded data. We usually generate a random IV and write it in front of the ciphertext. Since it is always 16 bytes for AES-CBC, you can slice it off during decryption. While your self-made padding scheme (multiple "n" characters) works in this case.
