Mule ESB provides various ways to secure your sensitive data. It is important to secure the data we send as it is possible that data can contain critical or sensitive information. For example, it is important to encrypt data like: credit card numbers, CVVs, passwords, etc. that we may send, so that our information cannot be retrieved by any hackers.
Private Key V/S Public Key
Private Key is also known as Secret Key and it is only known by the recipient of the message and is used to decrypt the message.
Public Key is used by the sender to encrypt the message before sending it to the recipient and it is known by everyone.
For example, Alice will use a public key to encrypt the data and send it to Bob. Now, Bob will decrypt the data using a private key.
XML Encrypter and Decrypter
It is used to encrypt strings and individual fields using xpath expressions.
JCE (Java Cryptography Extension) Encrypter And Decryter
It is used to encrypts streams, bytes, or strings.
PGP Encrypter and Decrypter
PGP (Pretty Good Privacy) encryption is used for encrypting, signing, and decrypting data like emails, text files, directories, and whole disk partitions, and it also increases the security of email communication.
BASE64 Encoder and Decoder
Base64 basically is used to encode and decode your data. As we need to secure our data, attachment, documents, etc. when we send them over the network. Base64 can encode your data before sending it off to its destination. Mule provides a Base64 encoder transformer for encrypting the data, and a Base64 decoder-transformer for decrypting the data.
Mule Credentials Vault
The Mule Credentials Vault is used to encrypt the data in a .properties file. Data is stored in the properties file as a name-value pair. It can store various information like usernames, passwords, and security tokens.
Now, you know the different ways of implementing data security with Mule ESB.
