In MSSQL if you create a hash variable with the HASHBYTES function and declare the wrong data type, it will be like this:

SET @password = HASHBYTES('SHA2_512', @password);

and get this as output "Ç­DË­v*] ¤RùèTýÁàç¥*8_#óê±Ø“ÔrcMúÇÓN¼5Ñj·ûŠÈ"

Correctly to do so:

DECLARE @hashedValue VARBINARY(8000) = HASHBYTES('SHA2_512', 'admin'

I need to somehow decipher the hashes that were stored as in the first example, that is not correct. ("Ç­DË­v*] ¤RùèTýÁàç¥*8_#óê±Ø“ÔrcMúÇÓN¼5Ñj·ûŠÈ"

how do I do that????

Examples of hashes which I need to decrypt:
