Caesar cipher
Shift every letter of a text by a chosen number of positions in the alphabet.
Caesar cipher is a free tool that runs entirely in your browser, with no data ever sent to a server. Shift every letter of a text by a chosen number of positions.
A historical cipher, not a serious one
The Caesar cipher replaces each letter with the one a certain number of positions further in the alphabet : with a shift of 3, A becomes D, B becomes E, and so on, wrapping back to the start after Z. Used by Julius Caesar according to legend, it doesn't hold up to modern computing analysis : only 25 possible shifts are enough to break it by brute force.
What this tool does not do
This tool only applies the transformation described above, with no spelling correction and no understanding of the text's meaning. A text of tens of thousands of lines is processed instantly ; beyond that, the only limit is your device's memory.
