You can easily share files with others using our unique key sharing feature, which can be used to precisely share and control who sees and uses the file. It can also automatically integrate and encrypt data on several cloud services such as Google Drive, Dropbox, and iCloud. Our intuitive and powerful standalone encryption software can encrypt data on desktops, smartphones and tablets. On the other hand, 3DES has been deprecated due to security vulnerabilities, while RSA's scalability and security make it the most widely used asymmetric encryption algorithm.ĪxCrypt utilizes the strong AES-256-bit algorithm to encrypt and decrypt data. Many government agencies, including the National Security Agency (NSA), rely on the AES encryption algorithm to protect their sensitive information. AES is used in many applications, including wireless security, processor security and file encryption, SSL/TLS protocol (website security), Wi-Fi security, mobile app encryption, and most VPNs. Overall, AES is considered safe, fast, and flexible, making it the most widely used encryption algorithm today. The difficulty of brute-forcing the key increases with each expanding key length, and RSA offers various encryption key lengths such as 768-bit, 1024-bit, 2048-bit, 4096-bit, etc The puzzle is to determine the original prime numbers from this giant-sized multiplied number. RSA's potency lies in the “prime factorization” method that it relies upon, where two huge random prime numbers are multiplied to create another giant number. It is widely used in many applications, including SSL/TLS certificates, crypto-currencies, and email encryption. RSA is an asymmetric encryption algorithm developed by Ron Rivest, Adi Shamir, and Leonard Adleman in 1977. The use of 3DES is set to be scrapped and discontinued in all new applications after 2023. In response, the National Institute of Standards and Technology (NIST) announced the deprecation of 3DES in a draft guidance published in 2019. However, the Sweet32 vulnerability exposed the security holes within 3DES. This process made 3DES much harder to crack than its predecessor, and it became widely used in payment systems, standards, and technology in the finance industry. The 3DES encryption algorithm is an upgrade to the DES or Data Encryption Standard algorithm, that applies the DES algorithm thrice to each data block. The number of rounds performed depends on the size of the key, which for AES is 10, 12, or 14 rounds.ģDES or Triple DES or Triple Data Encryption During the process, the text is scrabbled in multiple rounds. The encryption process involves several sub-processes, including sub bytes, shift rows, mix columns, and add round keys. Which means, the plaintext data is first broken into blocks or chunks, then substituted (replaced) and permutated (scrambled) over the course of several rounds using complex calculation, making the resulted ciphertext practically impossible to decipher. AES algorithm has key lengths of 128, 192, or 256 bits, which means it can convert a 128, 192, or 256 bits of text blocks at once.ĪES operates on the Substitution–Permutation Network (SPN), using a combination of substitution and permutation rounds to cipher the text. The AES encryption algorithm, also known as Rijndael, is a popular symmetric encryption algorithm used to protect data. This approach ensures that only the intended recipient, who has the private key, can decrypt the data.Īlthough asymmetric encryption is often deemed more secure than symmetric encryption, it can be slower and more resource-intensive.ĭifferent encryption algorithms have been devised based on the symmetric and asymmetric methods, and in this blog, we will discuss the three most popular ones: AES, 3DES, and RSA. The public key is used to encrypt the data, while the private key is used to decrypt it. The same key is shared between the sender and receiver of the encrypted data.Īsymmetric encryption, on the other hand, involves two keys: a public key and a private key. Symmetric encryption uses the same secret key for both encryption and decryption of the data. The rearrangement of text is backed by very intricate mathematical calculations known as a ‘key’, and the same mathematical calculations used for encryption are reversed to decrypt the text, allowing only the authorized individuals to access the original plain text.Įncryption methods essentially can be divided into two categories: symmetric and asymmetric. A computing device does this by running the text through one of the encryption algorithms, such as AES, to randomly rearrange and scramble the given text – making it impossible to read during the transmission. Encryption is a process of converting the plain text into an illegible text known as ciphertext.
