常见问题
What is character frequency analysis?+
Character frequency analysis counts how often each character appears in a text. In English, "E" is the most common letter (~13%), followed by "T" (~9%). This technique has been used in cryptography since the 9th century to break substitution ciphers.
Does it count spaces and punctuation?+
Yes, all characters including spaces, tabs, punctuation, and special characters are counted. You can toggle to exclude whitespace if you only want letter/digit frequencies.
