Functions

Dedicated HSM is a cloud service used for encryption, decryption, signature, signature verification, key generation, and the secure storage of keys.

Dedicated HSM provides encryption hardware, guaranteeing data security and integrity on Elastic Cloud Servers (ECSs) and meeting FIPS 140-2 requirements. Dedicated HSM offers you a secure and reliable management for the keys generated by your instances, and uses multiple algorithms for data encryption and decryption.

Functions

Dedicated HSM provides the following capabilities:

  • Generation, storage, import, export, and management of encryption keys (both symmetric and asymmetric keys)
  • Data encryption and decryption by using symmetric and asymmetric algorithms
  • Using cryptographic hash functions to calculate message digests and hash-based message authentication code
  • Signing data and code in encrypted mode and verifying signature
  • Random data generation in encrypted mode
