Abstract
A computer-implemented method (CIM), according to one approach, includes generating a primary cryptographic recovery key, and generating an alternate cryptographic recovery key, where the alternate cryptographic recovery key is generated and stored in a cryptographic Hardware Security Module (HSM). The method further includes storing an encrypted fallback key in metadata associated with a data set, where the encrypted fallback key is an operational key encrypted by the primary cryptographic recovery key, and storing a Recovery Key Verification Pattern (RKVP) in the metadata, where the RKVP is associated with the primary cryptographic recovery key and is stored for the primary cryptographic recovery key. In response to a determination that the operational key is unavailable, the encrypted fallback key is retrieved to perform a data decryption operation.
