Application of text and message security so that information confidentiality can be maintained, can also be used to secure whatsapp messages, twitter, instagram, facebook, SMS and other social media. 
FEATURES
1. Hashing:
used to randomize a message so it is not easy to read that goes in one direction, which means that the hash message cannot be decrypted again, this feature is perfect for validating a password. Existing methods include : MD5, SHA-1, SHA-2 (SHA224, SHA256, SHA384, SHA512), SHA-3 (Output Length can be adjusted), RIPEMD-160
2. Ciphers
Used to secure a text or message that goes both ways, which means the encryption and decryption process can be done and depends on the key that is used, the existing algorithms include : Caesar Chipper, AES, DES, Triple DES, Rabbit, RC4, RC4Drop (Drop depends on the key that is converted to decimal ascii then sum / merged)
3.Encoders
Encoders function to encode a text or message that goes both ways but does not require a key, the encoders method is as follows : Base64 and URL
4. Conversion
Conversion is used to convert a text message in ascii char format to a certain number base, or it can be used as a calculator from a number base. The conversion method includes :
a. ASCII Char to binary or octal or decimal or hex
b. binaries or octal or decimal or hex to ASCII Char
c. Or used for a base-number calculator
5. Morse Code
Library used: Crypto.js
