Crypt4Free — Overview
Crypt4Free is a small Windows freeware file-and-text encryption utility from InterCrypto/SecureAction (last public releases 2012–2016). It was created as a limited free version of Advanced Encryption Package (AEP) and is intended for encrypting files, encrypting text for email/IM, creating/extracting ZIPs, and securely wiping originals.
Key features
- Encryption algorithms: Blowfish (up to 448-bit) and DESX (128-bit)
- ZIP support: browse, extract, create archives; built-in compression
- Secure delete (file shredder / “Quick Wipe”)
- Encrypt text messages for e-mail/IM and send via MAPI clients
- Password/riddle hint field and password-strength meter
- Small installer (~3.5–4 MB), skinnable UI, tray agent, simple tools (password generator, history cleaner)
- Designed to decrypt files produced by AEP Pro as well
Compatibility & status
- Windows (XP through modern Windows versions reported on download sites)
- Project appears abandoned — last official versions dated 2012–2016 on public download sites.
Security notes (practical)
- Uses older algorithms and a limited set (Blowfish, DESX). These are not as modern or widely recommended as AES or authenticated-envelope schemes (e.g., AES-GCM, libsodium).
- No active development or recent security audits — avoid for high-sensitivity data or long-term protection.
- If you need free, actively maintained, well-reviewed alternatives, consider VeraCrypt (disk/volume), Gpg4win (OpenPGP for files/attachments), or modern tools that use AES/GCM or libsodium.
Where to get it
Available on archive/download sites (MajorGeeks, TechSpot, CNET/Download.com, Softonic) and the original vendor page (aeppro.com). Verify any download with antivirus/VirusTotal before running, since third‑party mirrors can vary.
Quick recommendation
Use Crypt4Free only for low-risk, short-term tasks where legacy compatibility matters. For stronger, actively maintained encryption choose VeraCrypt, Gpg4win, or other modern tools that use AES-GCM or libsodium.
