column.the mask.hash.hashAlgorithm.with.... data corruption occurs when using this feature. I've looked at the code.
Using ObjectOutputStream in the hash process causes data corruption.Because it performs a hash operation by adding abnormal characters to the front of the given value, the columns are corrupted and transmitted.Instead, a string conversion was performed and a byte array was obtained.
