Decrypted jpg file can't open about node-crypto-cli

[lutsifer]

I suspect the problem to be inside the string encoding part. I tried to alter it to base64:

function encrypt(encKey, content) { let iv_length = 16; let iv = crypto.randomBytes(iv_length); let cipher = crypto.createCipheriv('AES-256-CBC', Buffer.from(encKey), iv); let encrypted = cipher.update(content); encrypted = Buffer.concat([encrypted, cipher.final()]); return iv.toString('base64') + ':' + encrypted.toString('base64'); }

function decrypt(encKey, content){ let textParts = content.split(':'); let iv = Buffer.from(textParts.shift(), 'base64'); let encryptedContent = Buffer.from(textParts.join(':'), 'base64'); let decipher = crypto.createDecipheriv('AES-256-CBC', Buffer.from(encKey), iv); let decrypted = decipher.update(encryptedContent); decrypted = Buffer.concat([decrypted, decipher.final()]); return decrypted.toString(); }
It works well with text files etc, but it fails on jpg as before...
