Wrong checksum calculation in handleUploadPart

if (contentMD5String != null) { try { contentMD5 = HashCode.fromBytes( Base64.getDecoder().decode(contentMD5String)); } catch (IllegalArgumentException iae) { throw new S3Exception(S3ErrorCode.INVALID_DIGEST, iae); } if (contentMD5.bits() != MD5.bits()) { throw new S3Exception(S3ErrorCode.INVALID_DIGEST); } }

In handleUploadPart the code only checks for 128 bits and not the actual value, so even if someone sends a wrong MD5 base64 encoded string of file which is 128 bits the code will not throw an error.

This is for azureblob looks like we are not sending the actual content-MD5 received along with the Payload in case of azure
