You can't decrypt them, that's why it's called one-way. The only way to get the password is to encrypt guess words with the same algorithm and checking if the result matches the encrypted password. So if your encrypted password is a9d82da, guess what it might be - maybe "frank"? - and encrypt that word, and if you get 29d8afd, you know the password is not "frank", so try another word. If one of them encrypts into a9d82da, then you know that's the password.
Passwords are often guessed this way by using a dictionary - a simple list of words - and automatically encrypting them one by one and comparing the result with the encrypted password. Another approach that takes much longer is to try every possible combination of characters, such as aa, ab, ac, aaa, aab, aac, aba, abb, abc, etc. This can take weeks, months, even years, depending on the algorithm used and the speed of your computer.

What algorithm can't be reversed?
Hashing can't be reversed.
Which is better encryption algorithm among DES Blowfish and MD5?
MD5 isn't a encryption algorithm, it's a hashing algorithm. Encryption will 'hide' the meaning of the encrypted text, while MD5 will 'add up' all the text to come up with a number. This number can be compared to another time this file was 'added up', to provide a simple kind of check to see if the text has been changed or if it is the same.
What is Hash file organization in DBMS?
Hashing is the most common form of purely random access to a file or database. It is also used to access columns that do not have an index as an optimisation technique. Hash functions calculate the address of the page in which the record is to be stored based on one or more fields in the record. The records in a hash file appear randomly distributed across the available space. It requires some hashing algorithm and the technique. Hashing Algorithm converts a primary key value into a record address. The most popular form of hashing is division hashing with chained overflow.
What hash algorithm is used in NTLM?
NTLM (NT LAN Manager) uses the MD4 hash algorithm for hashing passwords. When a user sets a password, NTLM computes an MD4 hash of the UTF-16LE encoded password. This hash is then stored in the Security Account Manager (SAM) database. However, due to its vulnerabilities, NTLM is considered weak and has largely been replaced by more secure authentication protocols like Kerberos.
Difference between Internal hashing n external hashing?
Internal hashing mainly used for internal file, it is particularly an array of records. External hashing used for file disk
What is Homomorphic Hashing?
Homomorphic Hashing is a algorithm technique used for verifying data.
How does two-way hashing work to securely encrypt and decrypt data in a single process?
Two-way hashing uses a mathematical algorithm to convert data into a fixed-length string of characters, making it difficult to reverse engineer the original data. This process allows for secure encryption and decryption of data using the same algorithm, providing a way to protect sensitive information.
What algorithm can't be reversed?
Hashing can't be reversed.

What is SHA in Unix?
SHA is cryptographic hash function used to encrypt passwords. The SHA hashing algorithm is not restricted to Unix, though. It is typically used to verify the integrity of some downloaded file, to make sure there was no corruption during transmission. Your Windows or OSX software may use this same algorithm without you knowing it.
Which hashing algorithm is used to verify the integrity of data that has been transmitted over a network?
MD5
What you sthe bit length of any generated digest when using the MD5 hashing algorithm?
128 Bits
What are the security servics of cryptography?
Confidentiality, Integrity, Authentication, and Non-repudiationCryptography offers confidentiality and integrity of messages. Confidentiality ensures no one else can read your messages unless they have knowledge of the decryption key. Integrity is knowing the message is unaltered, and can be performed with either a trusted third party, hashing algorithm, or with public key cryptography.

In what way does the public key encrypted message hash provide a better digital signature than the public-key encrypted message?
A public key encrypted message hash provides a better digital signature because it ensures data integrity and authenticity with greater efficiency. By hashing the message first, only a fixed-size output is encrypted, which is faster and requires less computational power compared to encrypting the entire message. Additionally, the hash uniquely represents the message, allowing for easy verification; if the hash matches upon decryption, it confirms that the message has not been altered. This method is more secure as it reduces the risk of exposing the entire message during encryption.
What is the significance of ketama hashing in load balancing algorithms?
Ketama hashing is significant in load balancing algorithms because it helps evenly distribute incoming requests among servers based on a consistent hashing algorithm. This ensures that the workload is spread efficiently, preventing any single server from becoming overwhelmed.
What hash algorithm is used in NTLM?
NTLM (NT LAN Manager) uses the MD4 hash algorithm for hashing passwords. When a user sets a password, NTLM computes an MD4 hash of the UTF-16LE encoded password.
