Bloombase KeyCastle vs SAP Data Custodian Key Management Service

Bloombase KeyCastle manages cryptographic keys and certificate authority certificates, including private signing keys, public verification keys, authentication keys, and data encryption keys. It supports key creation, import, protected storage, verification, validation, inquiry, and deletion. Bloombase says keys stored in KeyCastle cannot technically be retrieved in plain form; its specifications say capacity is limited by available system storage, not a preset key count. Listed algorithms include AES, RSA, SHA hashes, Camellia, SEED, ARIA, and post-quantum options such as CRYSTALS-Kyber and CRYSTALS-Dilithium. KeyCastle supports PKCS#11 hardware security modules, OASIS KMIP, and a listed FIPS 140-2 compliant Bloombase Cryptographic Module. It connects with key services from AWS, Google, IBM, Microsoft Azure, and Oracle. Certificate functions include X.509 and PKCS#12 import and export, validity checks, retrieval, and revocation checks. Administration includes web and command-line consoles, central configuration, SNMP, and syslog. Optional high availability supports active-active or active-standby operation; recovery options include configuration backup and restore and recovery quorums. Pricing is on request, and Bloombase says customers may request a 30-day evaluation kit.

SAP Data Custodian Key Management Service is a cloud service accessed through the web for managing cryptographic keys. It supports three listed key types: AES, RSA, and ECC. Automated key rotation changes keys according to the service’s rotation capability, while key audit logs provide records of key-related activity. The service supports external key control and also lists a combined external-and-other control option, giving organizations more than one way to handle control of keys. Its deployment model is cloud, and its platform is web. SAP sells the service on a paid basis. Pricing is available on request, and no free plan is listed. Organizations can use the service as a web-based cloud option when AES, RSA, or ECC management, rotation, control choices, and audit logging are requirements.
