I am trying to store an Initialization Vector as a string hex, then retrieve it back to binary, but when I go to print the result to the console, it says the following:
fIV: undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined; Passphrase: passrig
Why is it printing undefined? And how can I achieve the desired result? Assume that the IV is generated correctly...
Relevant code:
SignIn(pass) { console.log(`fIV: ${h2b(fIV)}; Passphrase: ${pass}`); const key = crypto.scryptSync(pass, 'baethrowssalt', 32); var decipher = crypto.createDecipheriv(algorithm, key, h2b(fIV)); var decrypted = decipher.update(secret, 'hex', 'binary') + decipher.final('binary'); if(encrypted !== crypto.createCipheriv(algorithm, key).update(decrypted,'binary','hex') + cipher.final('hex')) { return alert(`access denied: encrypted:${encrypted}, secret:${secret}`); }; return Buffer.from(decrypted, 'hex'); } h2b(hex){ return (parseInt(hex, 16).toString(2)).padStart(8, '0'); }
Relevant snippet in the SignUp function, I am writing to the IV file with:
fs.writeFileSync(fileIV, iv.toString('hex'));
