Character frequency analysis

Character frequency analysis is a technique used to study how often each character appears in a text. By examining the counts of individual letters, digits, or symbols, analysts can identify patterns that reveal the text’s language, origin, or encryption. For example, in English, the letter 'E' occurs most frequently. This method helps in solving ciphers, verifying authorship, or understanding text characteristics. It’s like creating a fingerprint of a text based on its most common elements, providing useful insights without needing to read every word.
