A technique that is based on how frequently certain letters appear in English versus others. Frequency Analysis 8-bit values, up to 256 characters ASCII 16-bit values, up to 65,536 UTF-16 ECB, CBC, CFB, OFB, and CTR. Common block cipher modes include: -Most basic, weak , and unsecure -Each block is processed separately -No Salt or IV is used and the same key will be used to encrypt each block. This means if a given plaintext is encrypted in ECB and results in a given ciphertext, th...
