Text Encoding and Cipher Tools: Morse, Caesar, Braille

All text encoding tools

Binary Text Converter

Convert text to binary representation and decode binary back to readable text
Braille Translator

Convert text to Braille Unicode characters and translate Braille back to text
Morse Code Translator

Convert text to Morse code and decode Morse back to text with audio playback support
NATO Phonetic Alphabet

Convert text to NATO phonetic alphabet (Alpha, Bravo, Charlie) for clear communication
ROT13 Encoder/Decoder

Encode and decode text using ROT13 cipher substitution for simple text obfuscation
A1Z26 Cipher

Encode letters to numbers (A=1, Z=26) and decode number sequences back to text
Affine Cipher

Encrypt and decrypt with the affine cipher using multiplier and shift keys (a coprime to 26)
Autokey Vigenère Cipher

Encrypt and decrypt with the autokey cipher where the plaintext extends the keyword stream
Bacon Cipher

Encode text into Baconian a/b groups of five and decode Bacon cipher back to text
Beaufort Cipher

Encrypt and decrypt with the reciprocal Beaufort cipher using a keyword
Bifid Cipher

Encrypt and decrypt with the Bifid cipher combining a Polybius square with coordinate fractionation
Columnar Transposition Cipher

Encrypt and decrypt with keyword columnar transposition. Columns are read in alphabetical key order
Four-Square Cipher

Encrypt and decrypt digraphs using two keyword squares and two plain 5×5 squares. Round-trip guaranteed
Gronsfeld Cipher

Encrypt and decrypt with the Gronsfeld cipher using a numeric digit key
Keyword Substitution Cipher

Build a mixed cipher alphabet from a keyword and encrypt/decrypt monoalphabetic substitution text
Octal Text Converter

Convert text to octal representation and decode octal sequences to text
Playfair Cipher

Encrypt and decrypt with the Playfair digraph cipher using a 5×5 keyword square (I/J merged)
Polybius Square Cipher

Convert letters to row-column number pairs with the 5×5 Polybius square (I/J shared)
Rail Fence Cipher

Encrypt and decrypt text with the zigzag rail fence transposition cipher (2-10 rails)
ROT47 Encoder/Decoder

Encode and decode text using ROT47 cipher including numbers and symbols
Scytale Cipher

Encrypt and decrypt with the ancient Spartan scytale rod transposition cipher. Round-trip guaranteed
Tap Code Translator

Encode text as prisoner tap-code row,column taps and decode taps back to letters (K→C)
Text to ASCII Codes

Convert text to ASCII code numbers and decode ASCII codes back to readable text
Text to Unicode Points

Convert text to Unicode code points (U+0048 format) and decode back to characters
Caesar Cipher

Encode or decode text with the classic Caesar shift cipher
Vigenère Cipher

Encrypt or decrypt text using the Vigenère polyalphabetic cipher

About Text Encoding Tools

Text Encoding Tools gathers 28 classic codes and ciphers for puzzles, escape rooms, teaching and curiosity. Shift letters with the Caesar Cipher, use a keyword with the Vigenere Cipher, or build a 5x5 square with the Playfair Cipher. Rail fence, Bifid, four-square, Polybius, Bacon and affine ciphers are here too, along with Morse Code, tap code, the NATO phonetic alphabet and a Braille translator.

Each cipher encrypts and decrypts, and reversible codes are tested with round trips over accented letters, emoji and very long texts. Morse follows the ITU-R M.1677-1 standard, and binary, hex and octal text tools work on UTF-8 bytes so non-English text decodes correctly. These are historical or teaching ciphers that can be broken in seconds. Use them for fun and learning, and use proper encryption for anything that must stay private.

Frequently asked questions

Can a Vigenere cipher be cracked?

Yes. With enough text, methods such as Kasiski examination reveal the key length and then the key. It is a teaching cipher, not real security.

Which Morse code standard is used?

ITU-R M.1677-1, plus a few common extra symbols. Words are separated by a slash, and the decoder accepts dots and dashes in several styles.

Does the Braille translator support contractions?

It converts letters, numbers and punctuation to uncontracted Braille Unicode characters and back. It does not apply Grade 2 contractions.
