Troubleshooting AES_DECRYPT Failure in MySQL
When attempting to decrypt data previously encrypted with AES_ENCRYPT(), you may encounter an issue where AES_DECRYPT() returns an empty result. This can be frustrating, as your encrypted data remains inaccessible.
According to the MySQL documentation, AES_DECRYPT() is expected to return the original string após decrypting an encrypted string. However, in some cases, it may return a binary string instead.
To resolve this issue, try the following:
SELECT *, CAST(AES_DECRYPT(first_name, 'usa2010') AS CHAR(50)) first_name_decrypt FROM user
This query uses the CAST() function to convert the decrypted binary string to a CHAR string, which can be displayed properly. Instead of using "first_name" in your subsequent queries or applications, use "first_name_decrypt" to access the decrypted data.
The above is the detailed content of Why Does AES_DECRYPT() Return an Empty Result in MySQL?. For more information, please follow other related articles on the PHP Chinese website!
