Cipher

Encryption That
Actually Works.

Replace fragile key management with safe, automated cryptography. Varydn Cipher handles encryption, key rotation, and compliance so your team can focus on building.

cipher-sdk.js
// Simple, purpose-driven encryption
const cipher = new VarydnCipher();
// Encrypt with automatic key derivation
const encrypted = await cipher.encrypt(
'customer.email',
user.email
);
// Decrypt with version awareness
const decrypted = await cipher.decrypt(encrypted);
// ✓ Keys rotated safely
// ✓ Self-describing ciphertext
// ✓ Audit logs generated

Encryption Fails in Practice

Not because of weak algorithms, but because of operational complexity that compounds as systems scale.

Long-Lived, Shared Secrets

Keys stored in environment variables or config files are widely shared and never rotated.

Rotation Breaks Production

Manual key rotation is risky, disruptive, and often avoided until it's too late.

No Visibility Into Usage

Teams can't track which keys are used where, creating operational blind spots.

Developers Misuse Crypto

Cryptographic primitives are complex and easy to get wrong without proper guardrails.

Manual Compliance Work

Proving encryption practices for SOC 2, HIPAA, or PCI requires significant manual effort.

Future Crypto Migrations

Upgrading algorithms or migrating to post-quantum cryptography requires application rewrites.

Structured Key Hierarchy

Cipher uses a tiered key model that eliminates shared secrets and enables safe rotation.

1

Root Key (KMS/HSM-backed)

Never exposed. Stored in your cloud provider's KMS or hardware security module.

aws-kms://root-key-alias
2

Derived Key (scoped & versioned)

Deterministically derived from root key, scoped by purpose, tenant, service, and version.

purpose:customer.email | tenant:acme | v:2
3

Ephemeral Data Key (per operation)

Short-lived, randomly generated for each encryption operation. Maximum isolation.

AES-256-GCM | random-per-encrypt

What Cipher Delivers

A unified system for encryption, key management, rotation, observability, and compliance.

Simple API

encrypt("customer.email", value). Purpose-driven, standardized, and safe by default across all services.

Safe Key Rotation

Non-breaking rotation with dual-read support. New writes use latest version, old data migrates in background.

Self-Describing Ciphertext

Every encrypted value includes key version, purpose, algorithm, and context for safe migrations.

Crypto Observability

Track which keys are used where, how often, and detect stale or unused keys proactively.

Compliance Automation

Audit logs, rotation history, and policy enforcement evidence for SOC 2, PCI, HIPAA compliance.

Crypto Agility

Algorithm upgrades and post-quantum migration without application rewrites or downtime.

Built for Serious Systems

Designed for teams that have outgrown ENV-based secrets and need reliable, scalable encryption.

Perfect for

  • SaaS platforms handling sensitive customer data
  • Fintech and payments systems requiring PCI compliance
  • Healthcare and regulated environments with HIPAA requirements
  • AI and data platforms storing training data and models
  • Distributed systems operating across multiple regions or tenants

Especially if you

  • Have outgrown environment variable secrets management
  • Need reliable key rotation without production downtime
  • Face compliance requirements like SOC 2, ISO 27001, or FedRAMP
  • Want to reduce blast radius of potential key compromises
  • Are planning for post-quantum cryptography migration
