![]() You make your password “xt圓l6bqr8,” a suitably random collection of characters, and input it. Let’s imagine that you need to create a password to set up your account on a website. Salting a password is a simple process in which a plaintext password is combined with a random collection of numbers and letters. SHA-2 functions are now the most commonly used hashing algorithms. ![]() ![]() For example, SHA-256 produces a 256-bit hash value. Each algorithm in this category has a name reflective of its value length. This is a broad category or family of hashing functions. ![]() After security issues arose with the SHA hashing function, SHA-2 was developed. The algorithm has been supplanted by the more secure SHA-2 hash function. The secure hash algorithm (SHA) was a widely used hashing algorithm that could produce 160-bit hash values. The message-digest algorithm 5 (MD5) is a hashing function that produces a 128-bit hash value. Here are just a few of the most commonly used options: Many different password hashing algorithms, or hash functions, are available. Unlike encrypted data, hashed data cannot be unhashed the hashing process is irreversible, thanks to the algorithms used. However, if the website’s databases are hacked, all the hackers will get are the hashes, not the passwords themselves. If it matches the hash in the website’s records, the user can access their account. When a user tries to log in, the algorithm generates the appropriate password hash. Here is an example of what a hashing process might look like (in this example, the plaintext password is “xt圓l6bqr8”): Hash (“xt圓l6bqr8”) = 4n3920q25699841r05h5hg8h9w33nvlhg39501Ī website can store user password hashes instead of plaintext data. The hash may look to an observer like a random collection of numbers and letters, but it is created as a direct response to the plaintext input, so if you put the same text into the algorithm twice, you’ll get the same hash as a result. The length of this hashed password can vary depending on the kind of algorithm that you use to produce it. If you run a plaintext password (or any word or phrase) through a hashing algorithm, it produces a unique string of characters, sometimes referred to as a hashed value. Password hashing is a process in which algorithms turn plaintext passwords into complex strings of numbers and letters, known as ciphertext.
