WebMay 12, 2024 · An AES-CBC library can be used to obtain encryption with no padding, even if it is hardwired for one particular, by submitting plaintext of length multiple of the block size and removing the last block of ciphertext. Such library with hardwired padding can also be coerced to ignore the padding on decryption. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
