Ebean manual decryption

问题

I have successfully setup encryption for a field in my model using the answer provided in this SO post. But I would like to know how to manually decrypt the field from SQL client for debugging purposes. I want this information for Mysql (Prod database) and preferably for H2 (dev database). As per E-bean documentation Mysql uses AES_ENCRYPT/AES_DECRYPT and H2 uses ENCRYPT/DECRYPT functions.

  @Encrypted
  @Column(columnDefinition="varchar(50)")
  public String password;

Note: I have set the datatype of encrypted field as varchar instead of binary as shown below. Hence Ebean might additionally Hex the generated binary data.

class CustomEncryptKey implements EncryptKey{ 

   private String tableName;
   private String columnName;

   public CustomEncryptKey(String tableName, String columnName){
      this.tableName = tableName;
      this.columnName = columnName;
   }

 @Override 
 public String getStringValue() {     
        return "my-encryption-key";     
 }     
}

回答1:

I managed to Identify the answer. For My-SQL

to decrypt:

SELECT CAST(AES_DECRYPT(encrypted-field,'my-encryption-key') as CHAR(50)) from table

to encrypt:

SELECT AES_ENCRYPT(encrypted-field,'my-encryption-key') from table;

For H2:

encrypt:

ENCRYPT('AES', STRINGTOUTF8('<encryption-key>'), STRINGTOUTF8('<text to be encrypted>'))

decrypt:

TRIM(CHAR(0) FROM UTF8TOSTRING(DECRYPT('AES', STRINGTOUTF8('<encryption-key>'), '<text to be encrypted>')))
