iTop Password: Advanced Password Manager Built on Zero-Knowledge Encryption

While password managers are designed to safeguard sensitive information, concerns remain regarding their true reliability against data leaks. Powered by Zero-Knowledge Encryption, iTop Password completely blocks unauthorized access to your data and improves privacy.

In cryptography, Zero-Knowledge Encryption protects your data with a private key known only to you, meaning not even the password manager can access it.

End-to-End Encryption is the foundation of Zero-Knowledge architecture. The security method provides data security from the start to the finish. It encrypts data (usually by transferring plaintext to chiphertex) on the client-side before submission to the backend, keeping it protected in transit and at rest. Data is decrypted as plaintext only when a local authenticated session is established after the user provides verified email address and password.

Therefore, the server never stores plaintext passwords. All sensitive information and passwords keeps strictly protected via End-to-End Encryption.

What makes Zero-Knowledge encryption different from standard encryption architecture is that users have full control over the encryption key. A trusted password manager should ensure vault keys remain strictly under user control, completely inaccessible to the service provider.

But, not everything is secret. Zero-Knowledge Encryption may access some necessary information, like email addresses, as user identifier. That doesn’t violates the principles because Zero-Knowledge Encryption applies to confidential data. Password managers should adhere to Zero-Knowledge Encryption for vault information protection while addressing the practical realities of software, service and users. For instance, basic account information is essential for identification.

Is the data sensitive? The boundary is blurry. Some password manager providers retain unencrypted URLs and websites, making it possible for they to track users’ behaviors, from visited websites to access time and detailed logins.

iTop Password takes sensitive data more seriously, encrypting all information in a user's vault. Whether for website you visit or the names of local times and folders, it leverages Zero-Knowledge Encryption standards for enhanced security. You are always the only one to have the key of a completely encrypted vault. iTop Password cannot see your passwords, browsing histories and anything else stored in the vault.

In addition to Zero-Knowledge Encryption, iTop Password encrypts data using AES-256, an industry-standard symmetric encryption algorithm, and implements a dual authentication mode, which introduces Master Password verification to ensure that the vault data remains confidential even if the account password leaked. The master password is unknown expect yourself. If you loses the master password, iTop Password cannot recover it - a direct outcome of the Zero-Knowledge Encryption model.

With the support of PBKDF2 + SHA-256, iTop Password can generate derived keys from users' account and master passwords for vault information encryption.

It works as follows:

Mater password > Key Derivation Function > Encryption Key > AES-256 > Encrypted Vault

Therefore, the server primarily stores encrypted vault data rather than plaintext user passwords.

The Bottom Line

Better than common encryption architectures, Zero-Knowledge Encryption makes it impossible for password manager providers to access data in readable plaintext. In the future, Zero-Knowledge Encryption will deliver stronger protection for sensitive data without compromising usability and interoperability. iTop Password helps everyone achieve Zero-Knowledge Encryption with ease, available for both individuals and enterprises to well secure secret data and privacy.
