Now require encryption series such as:
8 digit string such as 00000001000000, 2000000, 3;
According to different encryption keys into the following string (such as length and 8 bits) :
89675749686384, 9986546, the encrypted string is haphazard and length, such as the encryption algorithm for symmetric encryption, can decrypt,
Please advise a better algorithm or way of thinking

CodePudding user response:

Such as long encryption algorithm, can use rc4, rc6

CodePudding user response:

For example, the key is a number, can use this number as a pseudo random number seed, generate a no repeat, for the whole sequence of pseudo random number, and then to the pseudo-random number sequence as a clock, to transform of plaintext, decryption according to the key to calculate the clock can be released, this is the original encryption methods, can keep clear of the frequency characteristics, see you in what occasion, wants much higher

CodePudding user response:

Such as length, the probability of AES is very high

CodePudding user response:

Mainly used in digital field in the database encryption
