The program task is to convert the genetic phonetic alphabet to 6 digits, we can use any well-remembered pinyin string, the transformation process is as follows, the first step, the string six a group of folding up, such as wangximing into: WangxiMingIn the second step, we want to add the ASCII value of all the characters perpendicular to the same position, and draw out 6 numbers, as the example above, then draw 228 202 206Then the number of each digit processing, that is, the number of each bit

into:WangxiMingThe second step. The ASCII values of all characters perpendicular to the same position are added to produce 6 numbers, as in the example above,It is concluded that:228 202 220 206 120 105The third step. And then the number of each digit "indent" Processing: the number of each bit is added, the figure if not aNumber, it is then indented until it becomes a digit. For example: 228 = 2+2+8=12 = 1+2=3The above number is reduced to: 344836, which is the final output of the program!Requ

Python implementation random cipher Dictionary Generator example

Originally wanted to be poor to lift all passwords, the algorithm is either nested too deep, or special consumption of memory (will overflow). Later, a simple algorithm with very low repetition probability was chosen. The code is as follows: Copy

Ultraviolet A 1339 cipher ent Cipher

Ancient Cipher Specified ent Roman Empire had a strong government system with varous parameters, including a Secret Service Department. important documents were sent between provinces and the capital in encrypted form to prevent eavesdropping. the most popular ciphers in those times were so called substitution cipher and permutation cipher. substitution

Comparison of sequence cipher and block cipher

The block cipher has a certain size as the base unit for each processing, while the sequence cipher is an element (a letter or aBITS) as a basic processing unit. A sequence cipher is an encrypted transformation that changes over time and has a conversion speedThe advantages of fast and low error propagation, the hardware implementation of the circuit is more simp

Symmetric encryption algorithm and pattern of block cipher

encryption algorithm, there is only one XOR between the plaintext group and the cipher group. The CFB mode is generated by using the XOR run of the "plaintext packet" and "output of the cipher algorithm" to generate the "ciphertext grouping". The bit sequence generated by the cryptographic algorithm in the CFB mode is called the key stream. The cipher algorit

Block cipher mode: OFB mode (output feedback mode)

In the OFB mode, the output of the cryptographic algorithm is fed back into the input of the cryptographic algorithm, and the OFB pattern is not directly encrypted by the cipher algorithm, but by XOR the output of the plaintext packet and cipher algorithm to create the ciphertext grouping, at which point the OFB mode and the CFB mode are very similar, as shown in:The difference between the OFB mode and the

Lock screen cipher algorithm parsing and decoding scheme in Android

First, prefaceRecently played King Glory, downloaded an auxiliary sample, the result was locked machine, of course, crack it is very simple, this later will be detailed analysis of this sample, but because this sample triggered by the desire is to parse the Android lock screen cipher algorithm, and then use an efficient way to make the lock machine malicious samples. Now the lock machine sample principle is too complex, meaningless. So this article fi
