WebNov 3, 2024 · 4. The question considers padding memorable text like "cipherkey" into an AES key by appending zero bytes to the (UTF-8) expression of this text as bytes, until reaching 16, 24, or 32 bytes for AES-128, AES-192, or AES-256. The main problem with this is that it's fast and inexpensive, which is a disaster in the context: it allows an adversary ... WebPython AES工具类 ECB模式+Pkcs7 padding.

PKCS#7 padding can always be removed because the last byte of the padded message tells you how much padding there is. If your original message is 02 02 02 ... 02 02, and the padded message is 02 02 02 ... 02 02 02 02, then you know that the last two bytes, and only the last two bytes, are padding. The other bytes are the actual message. the green acres school
