WebFeb 8, 2016 · I works because the padding bytes are not arbitrary bytes: they encode the length of the padding itself (see PKCS#7 padding). 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. WebApr 15, 2024 · Please note that we get decrypted bytes that are multiple of 16 bytes in size and padded. So, we need to first remove the padding and then decode() the bytes to get the plaintext. We are using the unpad() function from Crypto.Util.Padding for this purpose. And, then we are decoding the unpadded bytes to get the plaintext. radonmessung betrieb
