Bloombase KeyCastle vs Tencent Cloud 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.
