Encrypt password using JSP

[ghjk]

I have to develop a web application using JSP. I'm new to JSP. Could some one tell me how to encrypt password using JSP. I know php.

What do you mean by encrypt, do you mean mask it so noone knows what is being entered.

Are you using LDAP or is the password stored in a regular database?

[CODE=JAVA]

<input type ="password" id="passowrd"> should mask the password on your JSP

[/CODE]

Please stay tuned for a better answer on this one, if this is not it.

Just make a java class and call it in your jsp-page (or better struts-action).
If you are using this or older java versions than "JavaTM 2 SDK v 1.4", you can download the "JavaTM Cryptography Extension (JCE)".
In newer versions, these classes are already inside, see Java security classes

This is a code snippet randomly taken from the java API documentation:

Cipher aesCipher;
    
    // Create the cipher
    aesCipher = Cipher.getInstance("AES/ECB/PKCS5Padding");

We use the generated aesKey from above to initialize the Cipher object for encryption: 

    // Initialize the cipher for encryption
    aesCipher.init(Cipher.ENCRYPT_MODE, aesKey);
	  
    // Our cleartext
    byte[] cleartext = "This is just an example".getBytes();
	  
    // Encrypt the cleartext
    byte[] ciphertext = aesCipher.doFinal(cleartext);

    // Initialize the same cipher for decryption
    aesCipher.init(Cipher.DECRYPT_MODE, aesKey);
      
    // Decrypt the ciphertext
    byte[] cleartext1 = aesCipher.doFinal(ciphertext);
