12 sty 2013 · For PBKDF2, you can specify the length of the derived key. For scrypt, you can pick the first N bits of the output and use them as the key. The most straightforward way of doing this without using a KDF is to concatenate your passphrase with a 24 bit IV (initialization vector) and form an RC4 key.
While AES supports only block sizes of 128 bits and key sizes of 128, 192 and 256 bits, the original Rijndael supports key and block sizes in any multiple of 32, with a minimum of 128 and a maximum of 256 bits.
This is a small and portable implementation of the AES ECB, CTR and CBC encryption algorithms written in C. You can override the default key-size of 128 bit with 192 or 256 bit by defining the symbols AES192 or AES256 in aes.h.
C implementation of AES-128. No modes are given. This code has been tested with GCC 4.8.4 and Valgrind-3.11.0 on Intel-i5-3230.
22 kwi 2022 · I've implemented AES encryption in C to get more familiar with the language and to understand how encryption works better. I understand this code is unsuitable for actual cryptographic use and I'd ...
This repository provides a simple implementation of AES-128-CBC encryption and decryption in C using the AES_128_CBC.h header file. AES-128-CBC is a widely used symmetric encryption algorithm that operates on fixed-size blocks of data.
Key aspects of WEP include: Encryption: WEP uses the RC4 stream cipher for encryption. The standard supported key sizes of 64-bit and 128-bit, but in practice, these are actually 40-bit and 104-bit keys respectively, with the remaining bits used for an Initialization Vector (IV).
