Embodiments relate to digital data retention management. An aspect includes calculating a retention date associated with a data object in a storage system. Another aspect includes generating a cryptographic checksum for metadata relating to said data object, the metadata comprising the retention date. Another aspect includes storing said metadata and said cryptographic checksum. Another aspect includes, based on receiving a request to perform a deletion transaction on said data object for deleting said data object from the storage system: verifying metadata validity by checking the cryptographic checksum for the metadata associated with said data object to detect possible tampering of the metadata; verifying retention expiration by determining that a current date is past the retention date comprised in said metadata; and based on successful verification of metadata validity and retention expiration, authorizing deletion of said data object by the storage system |
