Data Integrity guides

Know-how, free

Practical data integrity knowledge from the same playbook HashAgent works from.

What a hash is, in plain terms

A fixed-length fingerprint of data. Why tiny changes produce completely different hashes.

Verifying a download with a checksum

Find the published checksum, compute your own and compare.

Choosing a hash function

SHA-256 and SHA-3 for integrity, bcrypt or Argon2 for passwords, and why MD5 and SHA-1 are retired.

Hash chains for audit logs

Each entry includes the previous entry's hash, making edits detectable.

FAQ

Questions buyers ask

Does HashAgent see my files?

The free check can run locally, so files never leave your machine. Paid services work from hashes and metadata where possible.

Is hashing the same as encryption?

No. Hashing is one-way and proves integrity; encryption is reversible and protects confidentiality.

Does it relate to crypto mining?

HashAgent focuses on data integrity. It does not run or monitor mining.
