Networking has some encryption algorithms for data transfer so that data cannot be stolen by unauthorized person. In current networking system there are many high security algorithms like 128 bit, 256 bit. But in ancient computer networking and military application there were no such powerful algorithms. They were used to transfer data using very simple algorithms. Some such algorithms and their encoder/decoders are available on some websites for fun/project research. It would be fun sometimes if you send such encoded message to your friend and leave him/her wonder what exactly you sent!
Morse Code: Morse code was a simple method to transmit data. Online encoder decoder for morse code is available. Morse code is a made of dot (.),dash(-) and space.
Morse code example:
- …. .. … .. … .- — — .-. … . -.-. — -.. . . -..- .- — .–. .-.. . –..– – . .-. .- -… ..- –.
You can use this converter to encode/decode your own message.
QR Code: Quick Response code. In today’s world also QR codes are used. Many mobile applications are available for encoding decoding QR codes. Basic use of QR codes is suggested by name itself. QR code is made of black and white lines. When you see a QR code, you need to take its picture from your mobile, the application will decode the code in seconds.
QR Code example:
You can use this encoder to encode your SMS, URL , text, number using QR code.
To decode QR code you can use cellphone application or you can use this tool to decode it online.
Binary : This is the coolest one. Why should we use English when computers only understands binary ? Lets talk in binary only. Online text to binary converters are available but the one who is not knowing it, oh my god! what the freaking 0 and 1 are.
P.S. please remove newlines if you don’t get a result.
To encode/decode text to binary you can use this tool.
Rotate 13: Rotate 13 is simplest encoding technique in which every character is shifted 13 positions.
Rotate 13 Example:
GrenOht vf ebgngrq 13 gvzrf
You can use this encoder/decoder for creating rotate 13 messages.
Vigenere Cipher: If you feel anyone can get your message by reverse rotating then Vigenere Cipher is correct thing for you. In this message is rotated as per key you enter. This makes your message more secure. Key is little hard to break.
Vigenere Cipher Example:
MiiaCom gimes ytvvppum omw slpa vhwks. Zia vee ebmoec jhblk mlvm
Let me tell you my key before you try to crack it: terabug is my key.
You can use this nice tool for Vigenere Cipher encode/decode.
There are many encryption decryption algorithms online. These are just a few. I want to save some for myself too. P-: . You can always have your own algorithm.
