Educational: What is End-to-End Encryption?

We hear about end-to-end encryption (E2EE) all the time—in messaging apps, file transfers, and secure storage. But what does it really mean?

In simple terms:

 End-to-end encryption ensures that only the sender and the intended recipient can read the data. Not even the service provider, hosting platform, or intermediary can decrypt it.

How it works:

• Data is encrypted on your device before it leaves.

• It travels across the network in encrypted form.

• Only the recipient’s private key can decrypt it.

• No third party (including the platform provider) has access to the plaintext.

Why it matters:

• Confidentiality: Your data isn’t exposed to service providers or attackers.

• ntegrity: If tampered with, the data won’t validate against the cryptographic keys.

• Trust: You don’t have to “trust” intermediaries—you trust the math.

For businesses, researchers, journalists, and nonprofits, E2EE means sensitive data remains private by design.

At ARegistry, we integrate E2EE with immutable storage—so your files are not only encrypted end-to-end, but also permanently preserved with verifiable integrity.
