When we make online purchases, write messages in a messenger or transmit any confidential information online, it is important for us to know that our data is securely protected and will not be used for criminal purposes. It is cryptography that helps to keep personal information intact using various encryption methods.
Cryptography is the science of data protection that uses social media marketing service encryption techniques to ensure the security of information. In simple terms, the encryption process looks like this: the sender encodes the data and passes the key to the recipient, with which he can decrypt it.
Common Cryptography Methods
Encryption is the process of transforming the original data into an incomprehensible form for outsiders. In order to open such a file, a key is needed, which is intended for decryption. Information can be encoded in different ways, for example, symmetric, asymmetric, hybrid or hash functions - let's look at each in more detail.
Symmetric encryption is a method in which one key is created to encode and decrypt data. This is an easy and convenient method, but it is not considered the most reliable, since both the sender and the recipient know about the key.
Asymmetric encryption is an algorithm that uses two different secret keys: public and private. The public key is used to encrypt data, and the private key is used to decrypt it. This method is more secure than the previous one: the private key is kept secret and is only available to the recipient.
Hybrid encryption is a combination of the two previous methods. The encryption process begins with using a public key to hide a message. This key is then encrypted using another public key, but decrypting it requires a private key that is known only to the recipient.
Hash functions - this method is interesting because the encoded data cannot be decrypted. It is used to store passwords, digital signatures or other confidential information. For example, when a user enters a password to access their personal account, the system applies a hash function to the password and compares the resulting hash with the hash stored in the database. If they match, the user gains access to the personal account. If not, he is denied.
