Tôi đang gặp vấn đề liên 泉 đến Encryption.Decryption sử dụng thuật toán mã hóa DES

这个是IDEA加密算法的源代码(C语言版本)-This is the IDEA encryption algorithm source code (C language version)

VHDL implementation of the twofish cipher for 128,192 and 256 bit keys. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.-VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.
