What Is Encryption?
Information can be converted into code using encryption, which conceals the true meaning of the data. Cryptography is the field of study that underlies both information encryption and decryption.
Unencrypted data is frequently referred to as plaintext data in the field of computing, while encrypted data is sometimes referred to as ciphertext.
The process of converting electronic data or signals into a secret code, which is a set of characters, numbers, or symbols that others cannot understand or use without specialized equipment, is another definition of encryption. It is a method of encrypting data such that only those with the proper authorization—more particularly, those with the right set of privileges—can access the actual message. In essence, it presents the unencrypted data given earlier as though it were random data. It needs the employment of a cryptographic key, which is a collection of numerical values that can be agreed upon by both the sender and the recipient of the encrypted message.
For instance, if you had "Cryptocurrency" in plaintext and it was encrypted, the ciphertext might end up reading SHSF#R𻨓, rendering it impossible to comprehend.
Although the encryption data may appear random to you, it actually follows a logical pattern that can be predicted, making it possible for a party that receives the encrypted data and has the correct key to decrypt it. This would make it plaintext again for that particular party.
A third party will be unlikely to be able to decrypt or break the ciphertext via brute force, or in other words, by using a bot that can try to guess the key itself, because the most secure encryption methods use keys that are sufficiently complex.
