Encipher It Chrome Extension Review: Strong Encryption or Overhyped?In an era where browser-based privacy tools are everywhere, the Encipher It Chrome extension promises a simple way to encrypt text inside your browser — protecting messages, notes, and form inputs with a click. This review examines what Encipher It does, how it works, its security model, usability, performance, alternatives, and whether it’s a worthwhile addition to your privacy toolkit.
What Encipher It Claims to Do
Encipher It is positioned as a lightweight Chrome extension that lets users encrypt and decrypt text directly in webpages, textareas, and web forms. Typical claims include:
- Quick client-side encryption/decryption without leaving the browser.
- Support for symmetric passphrase-based encryption.
- Integration with right-click context menu and toolbar buttons.
- Easy sharing of encrypted text via email or chat by pasting ciphertext.
Short fact: Encipher It mainly provides passphrase-based client-side encryption for text in the browser.
How It Works (Technical Overview)
Encipher It typically operates as follows:
- You install the extension in Chrome.
- When you need to protect text, you select it and choose the extension from the context menu (or open a pop-up).
- You enter a passphrase; the extension uses that passphrase to derive an encryption key and generates ciphertext which replaces the plaintext in the page or is copied to clipboard.
- The recipient uses the same passphrase with their Encipher It instance (or compatible tool) to decrypt the ciphertext.
Depending on the specific implementation, the extension may use common cryptographic building blocks such as AES for symmetric encryption and PBKDF2 or scrypt for key derivation. However, not all browser extensions disclose exact algorithms or parameter choices clearly.
Short fact: Security depends heavily on the extension’s crypto choices (algorithm, mode, key-derivation) and how it handles keys and random values.
Security Analysis — Strengths and Concerns
Strengths:
- Client-side encryption means ciphertext is produced before leaving your browser (when implemented correctly), reducing risks from network transit.
- Passphrase-based symmetric encryption is simple and broadly compatible for quick secure sharing.
Concerns:
- Transparency: Many extensions do not publish complete, verifiable cryptographic details or open-source code. Without that, you must trust the vendor.
- Key derivation: If a weak KDF (key derivation function) or low iteration count is used, passphrases can be brute-forced more easily.
- Passphrase sharing: Users often choose weak passphrases or share them insecurely (email, chat), undermining the protection.
- Implementation risks: Browser extensions can introduce vulnerabilities (insecure randomness, improper padding handling, ciphertext malleability, side channels).
- Updates and maintenance: If the extension isn’t actively maintained, discovered vulnerabilities may remain unpatched.
- Permissions: Extensions often require broad permissions (read/modify page content) — if compromised, they can access sensitive data.
Short fact: Encipher It’s security is only as strong as its cryptographic implementation, passphrase quality, and the extension’s integrity.
Usability and User Experience
What users typically like:
- Convenience: Encryption inside the browser removes context switching.
- Simplicity: A straightforward UI for encrypt/decrypt appeals to non-technical users.
- Integration with webpages: Encrypting textareas and forms is handy.
Common usability issues:
- Passphrase management: No built-in secure key storage means users must remember or manage passphrases externally.
- Lack of interoperability: If the tool uses a proprietary ciphertext format, recipients need the same extension/version to decrypt.
- UX clarity: Users might not be clearly informed about what is encrypted, where ciphertext is stored, or the consequences of losing a passphrase.
Short fact: Encipher It is convenient but places key management and safe passphrase practices squarely on the user.
Performance
For text-only encryption within a browser, performance is usually fast and imperceptible on modern machines. Large text blobs may take slightly longer, and excessive use on many pages could slightly affect browser memory usage, but these are minor in typical scenarios.
Short fact: For normal usage, performance impact is negligible.
Privacy and Permissions
Browser extensions often require permission to read and modify page content to operate. That access is necessary for encrypting/decrypting text in web forms, but it also means the extension could exfiltrate data if malicious or compromised. Always review requested permissions and prefer extensions with minimal scope and well-audited reputations.
Short fact: Required permissions can be broad — examine and trust the publisher before installing.
Compatibility and Interoperability
- Most passphrase-based symmetric approaches are interoperable if standards (e.g., AES with base64-encoded ciphertext and a clear KDF scheme) are used.
- If Encipher It follows a custom format, interoperability is limited to users of the same extension or compatible tools.
- No centralized server is needed for symmetric encryption, but secure out-of-band passphrase exchange is necessary.
Short fact: Interoperability depends on whether the extension follows common, documented formats.
Alternatives
Here are common alternative approaches depending on needs:
- End-to-end encrypted messaging apps (Signal, Wire) — for private communication with built-in key management.
- PGP/GPG — asymmetric encryption for email/files; more complex but robust and well-vetted.
- Browser-based open-source tools (OpenPGP.js, crypto libraries) integrated into mail clients or web apps.
- Other Chrome extensions with transparent open-source code and active audits.
Comparison table:
| Option | Ease of Use | Security (if used correctly) | Good for |
|---|---|---|---|
| Encipher It (extension) | High | Medium (implementation-dependent) | Quick text encryption in-browser |
| Signal / E2EE apps | High | High | Real-time messaging, voice/video |
| PGP/GPG | Low–Medium | High | Email, files, long-term trust |
| Open-source browser tools | Medium | High (if audited) | Developers, custom workflows |
Practical Recommendations
- If you want quick, occasional encryption of short text and trust the extension’s source, Encipher It can be useful.
- Don’t rely on it for high-value secrets unless the extension is open-source and the crypto parameters are published and reviewed.
- Use strong, unique passphrases (long, random or passphrases of multiple words) and share them via a secure out-of-band channel.
- Prefer tools with transparent, auditable implementations for sensitive use.
- Keep extensions up to date and regularly review permissions.
Short fact: For sensitive or high-value data, favor well-vetted cryptographic tools and established end-to-end encrypted services.
Verdict — Strong Encryption or Overhyped?
Encipher It and similar Chrome extensions offer genuine utility: simple client-side encryption for quick text protection. That said, whether they provide “strong” encryption depends on implementation details, maintenance, and user practices. Without open, audited code and clear specification of cryptographic parameters, the extension’s security guarantees remain limited by trust in the vendor.
Final takeaway: Encipher It is useful and convenient for low-to-medium risk scenarios, but for high-risk or high-value data, rely on proven, well-documented cryptographic tools and secure key management.
