Which Hash Algorithm to Use

MD5 — fast, widely supported, use only for non-security integrity checks
SHA-1 — legacy compatibility only, not recommended for new systems
SHA-256 — recommended for most file integrity verification use cases
SHA-512 — maximum security, use for highly sensitive files or long-term archival

The File Checksum Verifier on TechConverter.me processes files entirely in your browser — no data is ever sent to a server — making it safe to use even for sensitive files like configuration backups, private keys, and confidential documents.

Examples

Example 1: Verifying a Software Download

A developer downloads Ubuntu 24.04 LTS and wants to verify the ISO before installing. The Ubuntu download page lists:

ubuntu-24.04-desktop-amd64.iso
SHA-256: a435f6f393dda581172490eda9f683c32e495158a780b5a1de422ee77d98e909

They upload the downloaded ISO to the verifier, paste the expected SHA-256 hash, and click Verify:

File: ubuntu-24.04-desktop-amd64.iso
Size: 5.7 GB

Computed SHA-256:
  a435f6f393dda581172490eda9f683c32e495158a780b5a1de422ee77d98e909

Expected SHA-256:
  a435f6f393dda581172490eda9f683c32e495158a780b5a1de422ee77d98e909

Result: ✓ MATCH — file is intact and unmodified

Example 2: Detecting a Corrupted Download

A download was interrupted and resumed. The verifier detects the corruption:

File: software-installer.exe
Size: 124 MB

Computed SHA-256:
  7f83b1657ff1fc53b92dc18148a1d65dfc2d4b1fa3d677284addd200126d9069

Expected SHA-256:
  3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5f6a7b8c9d0e1f2a3b4c

Result: ✗ MISMATCH — file may be corrupted or tampered with
Recommendation: re-download the file and verify again

Example 3: Computing All Hash Types at Once

The verifier computes all supported hash algorithms simultaneously:

File: config-backup-2026-03-17.tar.gz
Size: 2.3 MB

MD5:     d41d8cd98f00b204e9800998ecf8427e
SHA-1:   da39a3ee5e6b4b0d3255bfef95601890afd80709
SHA-256: e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
SHA-512: cf83e1357eefb8bdf1542850d66d8007d620e4050b5715dc83f4a921d36ce9ce
