Why set a password using jasypt when encrypting text?
提问by blue-sky
To encrypt a password I use (modified from http://www.jasypt.org/encrypting-texts.html):
要加密我使用的密码（从http://www.jasypt.org/encrypting-texts.html修改）：
BasicTextEncryptor textEncryptor = new BasicTextEncryptor();
textEncryptor.setPassword(myEncryptionPassword);
String myEncryptedText = textEncryptor.encrypt(myText);
String plainText = textEncryptor.decrypt(myEncryptedText);
Why is a password required to be set on BasicTextEncryptor ?
为什么需要在 BasicTextEncryptor 上设置密码？
I may be not understanding something fundamental here but does this not make sense, although it does not work :
我可能没有理解这里的一些基本知识，但这没有意义，尽管它不起作用：
BasicTextEncryptor textEncryptor = new BasicTextEncryptor();
String myEncryptedText = textEncryptor.encrypt(myText);
String plainText = textEncryptor.decrypt(myEncryptedText);

It does work and it does require password for encryption and decryption. To simplify the example I have initiated two sessions of StandardPBEStringEncryptor as encryptor and decryptor
它确实有效，并且确实需要密码进行加密和解密。为了简化示例，我启动了 StandardPBEStringEncryptor 的两个会话作为加密器和解密器
public static void main(String[] args) {
StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
encryptor.setPassword("mySecretPassword");
String encryptedText = encryptor.encrypt("Hello World");
System.out.println("Encrypted text is: " + encryptedText);
StandardPBEStringEncryptor decryptor = new StandardPBEStringEncryptor();
decryptor.setPassword("mySecretPassword");
String decryptedText = decryptor.decrypt(encryptedText);
System.out.println("Decrypted text is: " + decryptedText);
}
output:
输出：
Encrypted text is: +pBbr+KOb7D6Ap/5vYJIUoHbhOruls+L
Decrypted text is: Hello World
