For public-key encryption, you must know either the public key (if the data was encrypted using the private key) or the private key (if the data was encrypted using the public key). For secret-key encryption, you must know both the key and IV that were used to encrypt the data. My initial reaction was why add the additional step of deriving a KEK to decrypt a key when you could just derive the original key. Thought that was mostly used when symmetric keys are encrypted with asymmetric keys. Note: The encoding used for encryption and decryption should be the same. Decryption is the reverse operation of encryption. The Key Encryption Key(KEK) is an interesting concept. Post converting the data into CSV format you can either write back to a CSV file or transform it in JSON format and send it in response. The additional parameters mentioned are optional to configure. Once the data is encrypted, you can write it into a file using the "write file palette." Decryption FlowĬonfigure MIME type in Set Payload as shown in the right-side figure. Once the keys are generated, you can configure them in the Mule 4 project. You can refer to Create PGP Keys to generate public and private keys. The result of the process is encrypted information (in cryptography, referred to as ciphertext). It is a best practice to have the contents of the file within quotes to avoid any misalignment of the data while reading.įor PGP encryption and decryption, one needs to have a public key to encrypt the data and a private key to decrypt the data. In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. We will encrypt and decrypt the following contents of a CSV file.
This blog will help you provide a step-by-step procedure to encrypt and decrypt a CSV file at source and destination. Securing this data while in transit is a key factor during data transmission. Many applications within an organization use CSV files to transfer huge data from one system to another. PGP (Pretty Good Privacy) is an encryption program that is used to encrypt and decrypt texts, files, e-mails, and directories. Within any organization, data security's role is to ensure the safety and security of private and commercial/finance data while minimizing exposure risk. It helps to prevent data breaches, reduces the risk of data exposure, secures sensitive data, and is highly recommended for the regulatory compliance process. Data security is an important aspect of the digital world.
