Many times, we use encryption without even realizing it in the many aspects of our daily lives. To avoid hackers intercepting and misusing our credit card information, it is encrypted when we make purchases online. In a similar vein, our passwords are encrypted when we access our social media accounts or email accounts to prevent identity theft. Chat apps also employ encryption to safeguard our exchanges and guarantee that our messages are only read by those we intend for.
Our financial and personal information would be open to theft and misuse in the absence of encryption. It’s critical to understand the fundamental ideas and terminology surrounding encryption. Fundamentally, encryption converts plain text into ciphertext by using mathematical formulas and keys. Two primary elements are usually involved in the encryption process: an encryption algorithm and an encryption key. An encryption algorithm is a collection of mathematical formulas and procedures that specify how to convert plaintext into ciphertext.
Different encryption algorithms exist, & each has advantages & disadvantages of its own. RSA, Blowfish, and Advanced Encryption Standard (AES) are a few frequently used encryption algorithms. A distinct bit of information called an encryption key is needed to both encrypt & decrypt data. For the purposes of the encryption algorithm, it is essentially a string of characters.

A passphrase, password, or character sequence generated at random can all be used as the key. In order to ensure the security of the encryption, the key’s length and complexity are vital. Longer & more complicated keys are typically more secure and difficult to decipher.
There are various encryption techniques, and each has advantages and disadvantages of its own. Symmetric, asymmetric, and hashing encryption are the three basic categories of encryption techniques. Employing the same key for both encryption and decryption, symmetric encryption is sometimes referred to as secret key encryption. This implies that the key for the encrypted data must be shared by both the sender and the recipient.
Because symmetric encryption is quick and effective, it can be used to encrypt big volumes of data. Symmetric encryption’s primary flaw, though, is the difficulty of safely exchanging the key between the sender & recipient. A pair of keys is used in asymmetric encryption, commonly referred to as public key encryption. These keys are the private key and the public key. While the private key is used for decryption, the public key is used for encryption.
The private key needs to be kept a secret, but the public key can be freely distributed to anybody. Sharing encrypted data is safer with asymmetric encryption since the private key is never disclosed. But compared to symmetric encryption, it requires more computing power and is slower. Data is transformed into a fixed-length character string, or hash value, using hashing, a one-way cryptography technique. Since the hash value is specific to the input data, the hash value will vary significantly even with slight changes to the input data.
Due to its ability to quickly verify passwords without storing the actual passwords, hashing is a popular method for password storage. Nevertheless, since the hash value cannot be undone to recover the original data, hashing is not appropriate for encryption. If you don’t use encryption to secure your data, there may be dire and extensive consequences.
Sensitive data is exposed to identity theft, data breaches, and unauthorized access without encryption. Cybercriminals and hackers are always searching for new ways to take advantage of holes in networks and systems in order to obtain important data. Cyberattacks have become more frequent in recent years, resulting in a rise in the number of data breaches at major corporations and organizations. Credit card numbers, names, addresses, social security numbers, and other personal information may become public knowledge as a result of these breaches.
Then, identity theft, financial fraud, & other nefarious acts could be committed using this information. For both individuals & companies, the financial and reputational harm resulting from data breaches can be disastrous. The 2017 Equifax breach, in which the personal data of about 147 million people was revealed, is a prominent illustration of a data breach. The affected people were exposed to financial fraud and identity theft because this breach contained names, social security numbers, birth dates, & addresses. The Equifax hack had a huge negative impact on the business, subjecting it to multiple legal actions and fines from authorities.
There are many important advantages to using encryption to safeguard your data. To begin with, encryption protects the privacy of your data by rendering it unreadable by unauthorized parties. This is especially crucial when sending sensitive data online, like credit card numbers or private medical records. With encryption, data is protected from being decoded without the encryption key, even in the event that it is intercepted. Second, encryption contributes to the preservation of your data’s integrity.
You can confirm that the data has not been altered during transmission or storage by employing encryption. Unauthorized changes to the encrypted data will lead to an invalid decryption, warning you about possible manipulation or corruption. Finally, data authenticity is ensured by encryption. The sender’s identity can be confirmed & data integrity can be guaranteed by encryption, which uses digital signatures and certificates. This holds especially true in situations like online banking or legal documents where credibility and trustworthiness are vital.
Sensitive data has been protected in the real world by encryption in the healthcare sector. Healthcare providers must encrypt patient data in order to protect patient privacy, per the Health Insurance Portability and Accountability Act (HIPAA). Patient data and medical records are kept private and secure thanks to encryption, which guards against potential breaches and unauthorized access.
