vernam cipher outputs in hexadecimal numbers
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am using the same Vernam Cipher algorithm both on the server side and front to encrypt/decrypt passwords. however I do get the correct value when I decrypt the encrypted password, the encrypted password is not in ASCII (8 bit) characters. I want to encrypt the password only into 8-bit ASCII and then want to send to/from the server but since the output is only a bunch of hexadecimal numbers which i assume are not ASCII, it's becoming difficult for me to send it over the network and save in a database. any help would be appreciated.
const crypto = {
key: 'catchmeifyoucan',
hash: function(string, key) {
const len = string.length
let ASCII = undefined;
let vernomChar = undefined;
let output = '';
if(this.key.length < string.length) {
this.key += this.key
}
for (let i = 0; i < string.length; i++) {
ASCII = (string.charCodeAt(i) ^ key.charCodeAt(i))
vernomChar = String.fromCharCode(ASCII)
output += vernomChar
}
return output
},
encrypt: function(string) {
return this.hash(string, this.key)
},
decrypt: function(string) {
return this.hash(string, this.key)
}
}
let encrypted = crypto.encrypt('text')
let decrypted = crypto.decrypt(encrypted)
console.log('encrypted',encrypted) // output: <0x17><0X04><0x0c><0x17>
console.log('decrypted',decrypted) // output: text

In JavaScript, strings are counted sequences of UTF-16 code units. (UTF-16 is a character encoding for the Unicode character set.) XOR-ing one with another could possibly create invalid code units or sequences. It definitely would work if both strings are from the C0 Controls and Basic Latin block plus the C1 Controls and Latin-1 Supplement block—but you should check your inputs.
