Can you explain how to securely hash data for encryption purposes?
To securely hash data for encryption, you can use algorithms like SHA-256 or bcrypt. These algorithms take the input data and produce a fixed-length hash value. This hash value can be used as a key for encryption. It is important to use a strong and secure hashing algorithm to protect the data from being easily decrypted.
What is a symmetric encryption?
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
What encryption algorithm is used to generate key in SSH?
SSH (Secure Shell) typically uses a combination of encryption algorithms to generate keys, with the most common being the Diffie-Hellman key exchange for securely exchanging keys over an insecure channel. It may also use elliptic curve algorithms (ECDH) for key generation. Once keys are exchanged, symmetric encryption algorithms like AES (Advanced Encryption Standard) are commonly employed for securing the session data. Overall, SSH employs robust cryptographic methods to ensure secure communications.
Where encryption done?
If we want to transmit the most secret data, we can use encryption process and transmit the data to the receiver. this process is called as encryption. regds nataraj
What encryption does a smart card use?
Smart cards typically use a combination of symmetric and asymmetric encryption. Common algorithms include AES (Advanced Encryption Standard) for symmetric encryption and RSA or ECC (Elliptic Curve Cryptography) for asymmetric encryption. These encryption methods help secure the data stored on the card and facilitate secure communication between the card and external systems. Additionally, smart cards often implement secure key management practices to protect sensitive cryptographic keys.
What is the use of an algorithm to scramble data into a format that can be read only by reversing the algorithm?
Encryption
Should i use encryption on my galaxy s5?
Yes, encryption will help to protect your phone and data.
Is it possible to encrypt a file in MD5?
MD5 is not an encryption algorithm; it is a cryptographic hash function used to create a fixed-size hash value from input data. While you can hash a file using MD5 to verify its integrity, this process is not reversible, meaning you cannot decrypt it. For encryption, you should use algorithms like AES or RSA, which provide mechanisms for securely encrypting and decrypting data.
What is crypto-encryption?
Cryptography or encryption are the two names of same technique and that is file encryption. File encryption is the best and most reliable and user friendly way to secure your data. Encryption software that are genuine and easy to use like Data Protecto and Folder Lock are ideal for encrypting your documents.
How to implement security in transient data?
Encryption and the use of digital certificates.
Why are people hesitant to use electronic payment system?
Because encryption doesn't seem possible until you learn that asymmetric algorithms exist.
What is the mathematical formula that is used in cryptography to encrypt data?
In cryptography, various mathematical formulas and algorithms are used to encrypt data, with one common approach being the use of symmetric key algorithms like the Advanced Encryption Standard (AES). AES relies on a series of mathematical operations, including substitution and permutation, applied to blocks of data using a secret key. Another widely used method is asymmetric encryption, such as RSA, which uses prime factorization as its mathematical foundation, allowing secure key exchange. Each algorithm employs distinct mathematical principles, but the overarching goal is to transform plaintext into ciphertext to protect data confidentiality.
