Answers to Questions

How to encrypt using Morse Code cipher?

Encryption assign to each letter, digit, or punctuation sign, a combinationhref of unique signal made of short and long impulsions (usually represented with a dot and a dash).

The complete table of Morse Code is in this grid :

DCODE is coded -.. -.-. --- -.. .

Impulsions can be electric, acoustic or luminous.

Messages sometimes starts with -.-.- (start of transmission) and end with .-.-. (end of transmission)

The code .-.-. is also the code for the character +.

Generally, when writing, each character is separated by a space and each word is separated by a slash /.

How to decrypt Morse Code cipher?

Decryption uses the same grid as encryption, but in order to accelerate the decryption process, some uses a tree like this:

How to recognize Morse Code ciphertext?

The ciphered message is mainly composed of dots and dashes (or sometimes, any other couple of characters).

Morse code is an auditive code, if one ears long and short bip sounds, it can be Morse

bip biiiip bip = .-.

Same with syllables in I or E for short and A or O for long.

TATITA = -.- (long, short, long)

How to decipher audio MP3 Morse?

One can listen the message and type simultaneously on a keyboard . (dot) for a short/acute sound and - (dash) for a long/grave one.

How to decipher Morse without spaces?

One can crack Morse without spaces, but hardly, possibilities are exponential. dCode has some tools, such as a brute-force attack or a dictionary attack.

What are the variants of the Morse Cipher?

It is possible to replace the two characters for short and long by others like A and B for example. It is even possible to switch them in order to fool the decoder.

There is a fairly well known overencryption: Fractionated Morsehref cipher.

What is the mountain Morse code?

A variant encodes morse with a kind of mountain profile:

How the Morse alphabet has been created?

There no real rules, however, frequent characters (E, T, A for example) are coded with short signals (1 or 2 impulsions). The letters less frequent are coded with 4 signals maximum, digits with 5.

How the learn the Morse alphabet with mnemonics?

Many methods are used, the principe is to remember 26 words, and with these word find the corresponding association between a letter and its code.

Here is a list of words where each vowel is a dot, each consonant is a dash.

V is described by oooh, that has three vowels and one consonanthref, so V is coded in Morse with ...-

Aax
Bbeau
Ccola
Dduo
Ee
Fuomo
Ggnu
Hoooa
Iio
Jiggs
Kkim
Lolei
Mvn
Nno
Opls
Pople
Qdrug
Rice
Sooo
Tt
Uear
Voooh
Warc
Xheat
Yhanz
Zblue

Another method used English pronunciation, stressed syllables standing for a dash and unstressed syllabes stands for a dot.

How to send a SOS in Morse?

SOS : ... --- ...

How to mark the end of a character in Morse?

In practice, when a letter is finished, the morse encodes the end of a character with empty sounds (silence) or empty visual a bit long. When retranscribing, one adds a slash / or any separating character.

When the Morse have been invented?

Morse Code has been invented in 1835 by Samuel Morse
