Online Morse code encrypt/decrypt tool

Chinese Morse code encrypt/decrypt tool: encrypts and decrypts Chinese text to and from Morse code; when decrypting, mind the separators between characters

Standard Morse code does not include Chinese characters; this Chinese Morse tool gets them via Unicode conversion


About Morse code | Morse Code

Morse code (Morse alphabet), also translated as Morse telegraphy code, is a signal code of alternating on and off

This signal code uses different arrangements to express different English letters, digits and punctuation marks

Morse code encryption characters are only letters, digits and punctuation, case-insensitive, and support Chinese characters

Invented in 1837 by the American Morse (Samuel Finley Breese Morse), making possible the 1835 invention of the Morse telegraph


Morse code light SOS | Morse Code

Morse code encoding is simple and clear with little ambiguity; characters are mainly formed by two symbols, "." and "-", one long one short

This is widely used in many cases, such as sending a distress signal

When sending distress signals with light in Morse code, define a long light as "-" and a short light as ".", and a flashlight's on/off switch can then send all kinds of messages, such as distress signals

If the light flashes in the pattern "short flash, dark, short flash, dark, short flash, dark, long flash, dark, long flash, dark, long flash, dark, short flash, dark, short flash, dark, short flash", it means the distress signal SOS

Because the Morse code of SOS is ... --- ... , light encoding can be done under the rules above. The encoding is actually very simple:Three short, three long, three short

Besides light, sound (two distinct sounds) can also be used to send a distress signal. This type of distress signal is worth knowing about and may come in handy when needed

How to use

This tool belongs to the “Encryption & encoding” category.

  1. 1Pick an algorithm: reversible ones are AES, DES and RC4; one-way digests are MD5 and the SHA family.
  2. 2Enter the text plus your key or salt. Encrypting twice with the same key must give the same result.
  3. 3Copy the output into your code. When comparing digests, match case and the 16/32-bit variant first.

Your input is processed locally in the browser whenever possible. We do not store it.

Frequently asked questions

Can MD5 be decrypted?

No. MD5 is a one-way digest — you can compare it, never reverse it. So-called "decryption" is a rainbow-table hit.

Why do two runs give different results?

Salts, random IVs, or a different case or source encoding all change the output. Normalise to UTF-8 before comparing.

Is it safe to paste a real key here?

Use it for learning and format checks. Generate and store production keys server-side; never paste a live secret into a web page.
