Code Diff Checker
Side-by-side text and script comparison engine with line-by-line syntax highlighting for comparing config files, build outputs, and code changes.
JSON Blob Utility
Paste malformed JSON payloads for real-time validation, automatic syntax repair (quotes, trailing commas), formatting, and tree navigation.
QR Utility

Zero Cloud Uploads.
Your Signing Keys Never Leave Your Device.
Most cloud signing services require you to upload your sensitive Apple Distribution .p12 certificates and Android .jks release keys to third-party servers.
**SignNext Studio** operates 100% locally. All credential passphrases, identities, and secrets are encrypted in sandboxed local storage using **hardware-seeded AES-256 encryption** (ENC::...).
// Local Hardware-Seeded AES Encryption Scheme
String encryptSecret(String secret) {
if (secret.startsWith('ENC::')) return secret;
final key = _deriveDeviceHardwareKey();
final encrypted = aesEncrypt(secret, key: key);
return 'ENC::${base64Encode(encrypted)}';
}
// Result in Vault Storage:
"p12Password": "ENC::aDk4M245czg3ZGZz...",
"keyPassword": "ENC::OTM4NDc1OTM4N2Rm..."AI Troubleshooting Assistant
