What is end-to-end encryption (or E2EE)?
End-to-end encryption ensures that only authorized users can access the data, not hackers, server administrators, institutions, service providers, ... In other words, it prevents the data from being breached when an unauthorized access happens, which is much stricter than encryption in transit combined with encryption at-rest.
The only E2EE platform
certified in the worldOur technology passed advanced penetration tests, with no security flaw detected.
Invisible and safe
for the end usersWe optimized our technology. Your users won't see the difference, but their data will.
No cryptographic skills
are requiredWe boiled down all the complexity into a ready-to-use toolkit for app developers.
Data security is broken.
Data breaches are wreaking havoc around the world, no need to enumerate hacks to convince you.
Traditional data security methods are not enough
Most of the time, security engineers focus their efforts on securing an application by creating a secure perimeter around it with measures such as a setting up WAF, TLS, encryption at-rest, PAM on the servers or using certified servers (ISO 27001, SecNumCloud).
Such an approach has its limits, it does not protect your data when an attacker breaches your application. The good news is that there is a way to protect data from unauthorized access: end-to-end encryption.
End-to-end encryption is hard to implement alone
End-to-end encryption is the gold standard to ensure data confidentiality, but it can be both hard and time-consuming to implement. Often, developers will try to use open-source libraries to implement it, but being low-level, it often makes them a poor fit for regular apps.
When building E2EE with an open-source cryptography library, one still needs to choose secure primitives, a robust RNG, implement a secure public key exchange, a private key recovery mechanism, groups management, multi-OS compatibility, ...
Seald allows to quickly integrate end-to-end encryption, with no expertise required.
Start encrypting data in minutes
Seald abstracted away all the cryptographic complexity to let you focus confidently on on what you know best: your product. Don't spend time on the choices of the primitives, key management, private key recovery, group management, ...
Did you know?
The Seald SDK is available for web, mobile or desktop applications and most languages.
The most effective technology to protect data
The Seald solution ensures the highest level of data security and privacy. End-to-end encryption protects you from data breach by encrypting data on the client side. If your servers are attacked, malicious people will not be able to access the encrypted data.
Did you know?
The Seald SDK follows the latest academic news in cryptography, it has been audited by specialized independent companies and has a certification from the French national cybersecurity agency.
Security-by-design for all applications
The Seald SDK can be integrated in all kinds of apps (collaboration, healthcare, legaltech and so on...) and encrypt structured or unstructured data in features like : chat, forms, file sharing & storage features, ... Your users won't notice the difference, our technology is fast and remains invisible.
Did you know?
Seald was developed on the zero-trust model, even in case of simultaneous breach of data encrypted by Seald and our servers, the confidentiality of the encrypted data remains assured.
Thanks to Seald, our Wimi Armoured solution guarantees the highest level of data security. A real competitive advantage, which allows us to target new markets.

import SealdSDK from '@seald-io/sdk'
// Initialize the SDK
const seald = SealdSDK({ apiURL, appId })
// Create your Seald identity
await seald.initiateIdentity({ signupJWT })
// Encrypt a message for another user
const encryptedMessage = await seald.encryptMessage(
'Super secret message',
