I wan to Decrypt a value that was encrypted in SQL server (using function Encryptbypassphrase). I am using 3DES algo.
I have the value of Pass-phrase. But i am unable to decrypt is using PassPhrase as key in my Java Application.
Later on i came to know that PassPhrase is used to generate a Key and key generation Algo is not open.
Can any one please confirm this or can suggest anyway to achieve this(Decrypting SQL encrypted value in Java).
Can i achieve this ? if i use EncryptByKey Function of MS SQL. But i am not sure if we can generate the KEY without any passphrase for EncryptByKey function.
Kindly suggest or guide...

I am reading the amazon key management system docs. I have tried to implement the encrypt and decrypt workflow by myself. I am using this java code to generate a custom master key like this:
private static SecretKey generateMasterKey() throws NoSuchAlgorithmException {
KeyGenerator keyGen = null;
keyGen = KeyGenerator.getInstance("AES");
keyGen.init(256); // 256 bit key
SecretKey masterKey = keyGen.generateKey();
return masterKey;
}
The next step is to use the custom master key to generate 2 types of key, the encrypt key and unencrypt key (I do not know how to explain the key name the right way, the key could encrypt the password for the next step). I want to use the unencrypt key to encrypt the password and store the password encrypt content and encrypt text in database. How to generate the encrypt key and unencrypt key from the custom master key? The two keys like the image:
I have mysql 8.0 database (collation utf-08).
Having Table tbl_test (collation utf-08.) with following field.
id int auto_increament
text varbarinary(100)
I have following values stored using Java's encrytion library
93e4431a51f1cdfd31e970e3e035b3d6
I am trying to decrypt using mysql 8.0. Here is my query
set #k = 'bisp123456pitbas';
set #iv = '7654gabasyd854f1';
SELECT id, CAST(AES_DECRYPT(text, #k, #iv) AS CHAR (150)) FROM tbl_test;
But always get empty result. It works in mysql 5.7.
Is there anyone can help me on this?
Looking forward.
I have encrypted password and stored into mysql table,actually couple of table are there to store different user credentials but column name(PASSWORD) is same in all tables.
There are so many scenario's are there in my project to connect different servers with user credentials.So My requirement is rather than decrypt password in all places(after select statement), need to decrypt in a common area ,it could be Listener or some thing.
When PASSWORD column find in select statement need to decrypt password.
please suggest how to achieve?
Thanks,
Raj
how can I simulate this code in mysql:
Encrypt
TextEncryptor encryptor = Encryptors.text(key, salt);
encryptor.encrypt(message);
Decrypt
TextEncryptor decryptor = Encryptors.text(key, salt);
decryptor.decrypt(message);
I need decrypt the data from the db that I encrytp in java code.
Use AES_ENCRYPT / AES_DECRYPT
INSERT INTO t VALUES (1, AES_ENCRYPT('text',UNHEX('F3229A0B371ED2D9441B830D21A390C3')));
https://dev.mysql.com/doc/refman/5.5/en/encryption-functions.html#function_aes-encrypt
Mysql offers a range of encryption functions, out of which only aes_encrypt() has not been deprecated yet.
However, if you want to encrypt data stored in databases, you may consider applying encryption on an operating system or database product level, so your data is encrypted, but you can still use sql to filter your data without much inconvenience.
We have a password column which stores from generated base64 hash. So when the user enters the password to login, it compares the password column in the database with the base64 of user password. But after migrating the data (using mysql mysqldump) from Linux to Windows 7, the passwords doesn't matches. Even though the passwords from the DB and the base64 hash generated from the password entered by User seems to be same. Do we need to do any additon steps in mysql while migrating the password column when migrating from linux to windows.
Note: When we migrate the data from linux to another linux it works, so we thought we should do unixtodos when migrating it from linux to windows. But still it fails.
We use java in the application
Code used to encode password
try
{
MessageDigest md = MessageDigest.getInstance("SHA-512");
md.update(password.getBytes());
byte[] raw = md.digest();
encodedPassword = (new BASE64Encoder()).encode(raw);
}
