Understanding PBE File Encryption
What is Password-Based File Encryption?

Password-Based Encryption (PBE) as specified in PKCS#5 (RFC 2898) allows you to encrypt files using a password instead of managing complex cryptographic keys. The password is combined with a salt and processed through multiple iterations to derive a secure encryption key.

How It Works
1. Upload File
Select the file to encrypt/decrypt
2. Password
Enter a strong password
3. Process
PBKDF derives key & encrypts
4. Download
Get encrypted/decrypted file
Security Recommendations
Recommended:
  • PBEWITHSHA256AND256BITAES-CBC-BC
  • PBEWITHMD5AND256BITAES-CBC-OPENSSL
  • Use 1000+ iterations
  • Use strong, unique passwords
Avoid:
  • PBEWITHMD5ANDDES (weak)
  • RC4-based algorithms
  • Low iteration counts
  • Simple or reused passwords
