11 Best Cryptography Tools in 2022

Computing systems requiring cryptography tools are deeply ingrained into modern human lifestyles and business practices. Specifically, digital technologies are applied in every domain, including healthcare, security, transportation, marketing, banking, and education. As a result, data has become a vital asset. In addition, companies require data to derive business value, whereas attackers target data for monetary and other gains. That said, organizations need reliable methods to secure sensitive information and maintain data integrity and confidentiality.

Fortunately, cryptography and encryption methods have been used for centuries to prevent prying eyes from accessing secret messages. Also, strong encryption has become one of the most crucial cybersecurity practices for supporting modern internet communications. Encryption algorithms convert original data in plain text to an encrypted message to ensure secure transmission. Users use an encryption key to turn plain text into a block cipher, and recipients must access a correct decryption key to view the encrypted information in its original state.c

Cryptographic algorithms assist companies and individual users in achieving secure communications and robust internet connections to strengthen privacy. In addition, cryptography tools make it harder for malicious actors to break encryption algorithms, preventing unauthorized persons from accessing sensitive data. Therefore, modern cryptography focuses on four primary information security goals:

  • Data integrity: Cryptography tools protect data from unauthorized modification in transit or at rest, thus preserving its integrity.
  • Data confidentiality: Only individuals with the correct decryption key can access encrypted data. Encryption tools prevent unwanted access, which is vital in ensuring data confidentiality.
  • Authenticity: Data encryption provides senders and recipients with a way of verifying each other to verify their authenticity.
  • Non-repudiation: File encryption ensures non-repudiation, implying that a message sender cannot deny or backtrack that they sent the message.

Different Types of Cryptography

The different encryption techniques can be categorized into hash functions, public-key cryptography, and secret-key cryptography. Hash functions are one-way, irreversible cryptographic functions that ensure data protection by making it impossible to recover the original data. Essentially, hashing is a technique used to transform data of a given string into a cipher block of a fixed-length string. An efficient hashing algorithm converts a specific input into a secure and unique output. If an attacker attempt to crack a hash function, the only approach is attempting all possible inputs until they can get the corresponding hash. Hash functions are often used to hash data like passwords and certificates. Common examples of hashing functions include MD5, SHA-1, SHA-3, and Whirlpool.

On the other hand, public-key cryptography also referred to as asymmetric cryptography, is a cryptographic technique that uses two keys to encrypt data. A public key accessible to everyone allows the sender to encrypt the data while the recipient uses a private key, only known to the recipient, to decrypt the data. In contrast to symmetric encryption, the key used to encrypt the data cannot decode it. The private key is private to the recipient, whereas the public key can be shared publicly with anyone. As such, the private key should only remain with the owner. Common examples of public-key cryptography are Diffie-Hellman and elliptic curve cryptography.

Lastly, the secret key cryptography technique, also called symmetric cryptography, is an encryption approach that uses a single key for both data encryption and decryption. Symmetric cryptography uses the same encryption and decryption key, making it among the simplest cryptography methods. A symmetric cryptographic algorithm uses an encryption key to convert original text into ciphertext, whereas the recipient entrusted with a secret key can decrypt the data. In this regard, secret key cryptography can be used in encrypting data in transit and at rest. Examples of secret key cryptography include advanced encryption standards (AES) and Caesar cipher.

9.      Key-Based Authentication

Key-based authentication is an encryption technique that employs an asymmetric cryptographic algorithm to verify a user’s identity and is often used as an alternative for password authentication. Private keys and public keys are the primary factors at play used in confirming a client’s identity. When authenticating users using the public key authentication method, each user is provided with a pair of asymmetric keys. The users then store the public keys in the system for data transfer while retaining their private keys in the respective devices connected to the secure system. During key management and key exchange, the secure server authenticates clients with the public keys and requires the users to use the corresponding private key to decrypt the message.

10. Authentication Token/Security Token

A security token or authentication token is a cryptography tool used in verifying a user. For example, a company uses the security token cryptographic tool to authenticate users. In particular, a security token encrypts the exchange of secure authentication information. Organizations also use the authentication tool to HTTP protocols with complete statefulness. As such, a web browser utilizes server-side generated tokens such that it can continue with the state. Generally, a security token is a method used to ensure remote authentication. Authentication information is sensitive and should be encrypted to prevent unwanted access or modification. A security token provides the relevant encryption scheme to enable secure user remote authentication.

In addition, Docker encrypts information and files, thus preventing individuals lacking the correct decryption key from accessing it. The cryptographic methods used to encrypt the data vary depending on encryption attributes. Moreover, companies consider Docker a cloud storage solution that permits users or developers to manage encrypted data on a shared or dedicated server. In simple terms, a Docker container enables users to hold sensitive data and ensure its security through encryption to focus resources on application development.
