In their own words
AWS Key Management Service
AWS Key Management Service creates and controls cryptographic keys for data encryption and digital signatures. It centralizes key lifecycles and permissions, including separate control over administrators and key users. KMS supports symmetric encryption, asymmetric signing or encryption pairs, and HMAC generation and verification. The AWS Encryption SDK can use KMS as a key provider for local application encryption and decryption. Integrations include Amazon S3, EBS, RDS, DynamoDB, Lambda, and CloudTrail. With CloudTrail enabled, requests can record the user, time, API action, and key. AWS says hardware security modules validated to FIPS 140-3 Security Level 3 protect key material and operations, with plaintext keys kept only in volatile HSM memory. Multi-Region keys support cross-Region workflows; external key stores keep material in a customer-managed external manager. KMS scales with demand but has default key and request limits. The listed plan is $1 a month per KMS key, prorated hourly.
Cryptsoft KMIP Server
Cryptsoft KMIP Server is a C and Java SDK for developers adding key-management server capability to their own products. The SDK supports KMIP versions 1.0 through 2.1, with KMIP 3.0 support also listed, and Cryptsoft describes it as OASIS KMIP compliant. The company says its SDKs connect with HSMs, key-management servers, cloud services, storage and embedded devices, and support HSM integration and policy control. Keyward is a rebrandable web console for the server; it offers two layouts, theming, passkey sign-in and nine languages, and communicates over native KMIP or REST. Cryptsoft says KMIP 3.0 supports ML-KEM, ML-DSA and SLH-DSA through OpenSSL 3.5+ for C or Bouncy Castle 1.81+ for Java. The server can also deliver quantum key distribution material through KMIP as an ETSI-compliant key management entity. Linux and Windows are listed, with custom platform ports available on request. The product is intended for OEM integration; pricing and licensing details require contacting Cryptsoft.
