Encryption

Encryption

An index and topic collection covering encryption services, key management systems (KMS), hardware security modules (HSM), envelope encryption, end-to-end encryption SDKs, certificate management, and code/data signing. This topic gathers the cryptographic primitives, managed services, and open-source libraries that protect data at rest and in transit across cloud, mobile, web, and supply-chain workloads. It includes managed KMS offerings (AWS KMS, Google Cloud KMS, Azure Key Vault), HSM and enterprise key management platforms, secrets and configuration encryption tooling (HashiCorp Vault, Doppler, SOPS), code- and artifact-signing infrastructure (Sigstore, Cosign, Notary, TUF), end-to-end encrypted messaging protocols (Signal, Matrix), and certificate authority APIs (Let's Encrypt, DigiCert, Amazon Private CA). Distinct from the broader Security topic, this collection focuses specifically on cryptography, keys, certificates, and signing.

extensionCommon Features

extensionManaged Key Management Services

Cloud KMS offerings like AWS KMS, Google Cloud KMS, and Azure Key Vault provide managed creation, rotation, and lifecycle of cryptographic keys with hardware-backed protection and IAM-controlled access.

extensionHardware Security Module APIs

Network-attached HSMs and HSM-backed services such as AWS CloudHSM, Azure Dedicated HSM, and Google Cloud HSM expose tamper-resistant cryptographic operations through PKCS#11 and REST APIs.

extensionEnvelope Encryption Patterns

Envelope encryption wraps data encryption keys (DEKs) with key encryption keys (KEKs) stored in a KMS, enabling scalable encryption of large data sets while centralizing key control.

extensionEnd-to-End Encryption Protocols

Open protocols like Signal, Matrix Olm/Megolm, and MLS provide forward-secret, deniable end-to-end encryption for messaging, calling, and collaboration applications.

extensionCertificate Lifecycle Automation

ACME-based services like Let's Encrypt, alongside enterprise CAs like DigiCert and Amazon Private CA, automate issuance, renewal, and revocation of TLS and code-signing certificates.

extensionCode and Artifact Signing

Sigstore, Cosign, Notary, and TUF provide keyless and key-based signing of container images, binaries, and software packages with transparency-log-backed verification.

extensionSecrets and Configuration Encryption

Tools like HashiCorp Vault, Doppler, and SOPS encrypt secrets, environment variables, and configuration files in transit and at rest, integrating with KMS providers and CI/CD pipelines.

extensionOpen-Source Cryptographic Libraries

Libraries like Google Tink, libsodium, OpenSSL, and BoringSSL provide misuse-resistant primitives for symmetric, asymmetric, AEAD, hashing, and digital signature operations.

task_altUse Cases

task_altEncrypting Data at Rest in the Cloud

Applications use cloud KMS APIs to encrypt database fields, S3 objects, and disk volumes with envelope encryption, ensuring keys never leave a managed boundary while data ciphertext can be stored anywhere.

task_altTLS Termination and Certificate Renewal

Web platforms automate TLS certificate provisioning and rotation through ACME (Let's Encrypt) or enterprise CA APIs (DigiCert, Amazon Private CA), keeping in-transit encryption healthy without manual operations.

task_altSoftware Supply Chain Signing

Build pipelines sign container images and binaries with Sigstore/Cosign, anchoring artifacts to transparency logs so downstream consumers can verify provenance before deploying.

task_altEnd-to-End Encrypted Messaging and Collaboration

Messaging applications integrate Signal protocol, Matrix Olm/Megolm, or MLS to provide forward-secret encryption where neither the service operator nor an attacker can read message content.

task_altSecrets Management for CI/CD

HashiCorp Vault, Doppler, and SOPS encrypt secrets used across CI/CD pipelines, source control, and runtime environments, integrating with cloud KMS for sealed storage and audit logging.

task_altTokenization and Payment Cryptography

Payment processors and PCI workloads use services like AWS Payment Cryptography and Apple Pay tokenization to perform PIN translation, card encryption, and EMV operations under FIPS-validated HSMs.

task_altWorkload Identity and Zero-Trust Cryptography

SPIFFE/SPIRE issue short-lived, cryptographically verifiable workload identities (SVIDs) so services can mutually authenticate without long-lived secrets across multi-cloud environments.

integration_instructionsIntegrations

integration_instructionsAWS KMS

Managed key creation, envelope encryption, and HSM-backed cryptographic operations integrated across AWS services and accessible via SDK and REST APIs.

integration_instructionsGoogle Cloud KMS

Multi-region, software- and HSM-backed key management for envelope encryption and signing across GCP services and external KMS scenarios.

integration_instructionsAzure Key Vault

Centralized key, secret, and certificate management with HSM-backed key protection and tight integration into Azure services and Entra ID.

integration_instructionsHashiCorp Vault

Open-source secrets management with a Transit engine for encryption-as-a-service, PKI engine for certificate issuance, and KMIP server for HSM integration.

integration_instructionsSigstore

Free, keyless software signing infrastructure built around Fulcio (CA), Rekor (transparency log), and Cosign (signing CLI), now broadly used for OSS supply chain integrity.

integration_instructionsLet's Encrypt

Free, automated ACME-based certificate authority issuing billions of TLS certificates that underpin in-transit encryption for the public web.
