Today, it is more important than ever to protect information systems<\/strong>. We must comply with confidentiality standards<\/strong> and protect ourselves against cyberattacks, which can lead to massive data leaks or paralyse our information systems<\/strong>.<\/p>

In this article, we will discuss one of the best practices to adopt right now: the encryption of confidential data.<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Data encryption involves scrambling data into a secret code that can only be unlocked with a unique digital key. <\/span>There are two main methods of encryption: <\/span><\/p>

\u2013 Symmetric encryption<\/strong>, in which messages are encrypted and decrypted using the same key. This is the oldest method of encryption. Evidence of its use can be found in Ancient Egypt.<\/span><\/p>

\u2013 Asymmetric encryption<\/strong>, considered the most secure method because it is very difficult to corrupt, as explained below.<\/span><\/p>

\u201c\u201cKey management is a crucial process in the configuration of a cryptographic system, and becomes even more complex as the volume and distribution of data and the number of actors involved are significant.<\/em>\u201d \u2013 CNIL (French Data Protection Authority) <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Public keys and private keys: what are they? \n\n<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Asymmetric cryptography is based on a two-key model, a public key and a private key, often represented by a lock (public key), with the private key opening the lock. The public key is only used to encrypt the document, while the private key is used to decrypt it.<\/p>

The owner of the private key can retrieve the public key to access their private data, but the reverse is impossible because the principle is based on complex mathematical operations. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Now that we know that data encryption is one of the essential practices for protecting the confidentiality of sensitive information, let's take a look at how bad behaviour can undermine its effectiveness.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

How can you be sure that the \u2018secrets\u2019 are properly encrypted?<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Secrets<\/strong> are a specific term in cybersecurity used to refer to sensitive data<\/strong> that must not be disclosed under any circumstances, as this could harm the company's business activities. Examples include passwords, API certificates and digital certificates<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t

One way to encrypt secrets is to use base64<\/strong> encoding. This is an algorithm that converts text into a string of characters consisting of letters, numbers and symbols.<\/p>

For example:<\/em><\/p>

Password: 123456<\/p>

Encoded in base64 : VGhpcyBpcyBhIhRlc482c2Q<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

However, this encoding is not a secure method because if someone has access to the base64 encryption code, using tools or software, they can decrypt the secret message and read it. It is therefore recommended to use a more robust algorithm such as asymmetric encryption, as discussed above. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

When storing data in a public cloud, we use keys that are managed by default by the cloud provider<\/strong>.\nFor example, you can use a virtual safe, known as a vault. Often provided by a cloud provider or external service provider, this safe is presented as a complementary solution. However, it is important to note the disadvantages of this method:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
