Redis uses this hash digest for efficient comparison operations without needing to compare the full string content. You can retrieve a key's hash digest using the [`DIGEST`](https://redis.io/docs/latest/commands/digest) command, which returns it as a hexadecimal string that you can use with the `IFDEQ` and `IFDNE` options, and also the [`SET`](https://redis.io/docs/latest/commands/set) command's `IFDEQ` and `IFDNE` options."
