Poj2159 comment ent CipherPreface The English language is poor, and the ac is hard to learn 555. For example, the water question recommended by Daniel is very excited. After reading it, I feel wrong when preparing to write the code. I decided to go to the comment area and read = pitfall. Fortunately, there is no direct code, and the question is directly understood wrong! Do you understand this, comrades? → _ →Question Ancient Cipher Time Limit: 10

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 subs

First, the principle:CTR Mode is a stream cipher that generates a key stream by encrypting successive accumulated counters, and in CTR mode, each packet corresponds to a successive cumulative counter, and the key stream is generated by encrypting the counter. The final cipher packet is obtained by XOR the bit sequence encrypted by the counter and the plaintext packet.Second, schematic diagram:Three, the adv

If the same plaintext letter in a different position in the clear text is the same as the corresponding ciphertext in the ciphertext, it is called a single-table cryptosystem.Representative single-table password:1. Shift or add password2. Multiplier or multiplication password3. Affine password4. Key phrase passwordHere is an example:1. Addition Cipher algorithm:P=c=k=zm (zm∈{0,1,..., m-1})Ek (x) =x+k (mod m) =y∈cDk (y) =y-k (mod m) =x∈pWhen k=3, the

Suning Tesco server supports EXP cipher suite for ssl freak attacks to decrypt communication traffic (including poc) Suning Tesco server is vulnerable to ssl freak attacks because of its support for EXP cipher suites. intermediary users can decrypt communication traffic online (obtain sensitive information such as login creden) The server accepts three export-level ciph
