How to send MD5 encrypted password to Server in jsp

The MD5 Message-Digest Algorithm is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value.

Below this image i am showing you. How to send md5 hash Encrypted data to Server. You can also use other Hash Algorithms like ( SHA, SHA1, SHA256, SHA512 )

It is very necessary to encrypt the data. When you are sending data throw URL.

MD5 Encrypt Hash in JavaScript

The MD5 Message-Digest Algorithm is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value.

The md5() function (presented in this page) can be used in JavaScript to calculate the MD5 hash of a string. Returns the hash as a 32-character hexadecimal number.

SHA1 Encrypt Hash in JavaScript

The SHA (Secure Hash Algorithm) can be used to encrypt data for secure transfer between applications and server.

The SHA1() function returns a string with the SHA1 encrypted hash as a string with 40 characters.

It is fully compatible with UTF-8 encoding.
