I wonder if we could use a more descriptive string here. "BLAKE2" will be meaningless to most users. Maybe "Checksum" ?

I did not include the word "checksum" for BLAKE2 because I wanted to follow the example of "CRC". But it is true that CRC is more well-known than BLAKE2. Which of the following option is better in your opinion?

1. Add the word "checksum" to both CRC and BLAKE2:

        case CRC:
	​            return i18nc("CRC hash code", "CRC checksum");
​        case BLAKE2:
	​            return i18nc("BLAKE2 hash code", "BLAKE2 checksum");

2. Add the word "checksum" to BLAKE2 only:

        case CRC:
	​            return i18nc("CRC hash code", "CRC");
​        case BLAKE2:
	​            return i18nc("BLAKE2 hash code", "BLAKE2 checksum");
