What Is SHA-256 and How To Calculate In Python, PHP, JavaScript, Go, Java, PowerShell Programming Languages?

Hash algorithms are the heart of the cryptography and security. SHA-256 is a Secure Hash Algorithm which will generate an output hash value in 256 bit. SHA-256 is designed by the National Security Agency (NSA). SHA-256 is one of the cryptographic hash functions. SHA-256 is also named one-way function where the generated hash value cannot be reversed theoretically. This makes SHA-256 very useful for password validation, challenge hash authentication, anti-tamper,...

What is Checksum and Related Tools with Calculation Examples

checksum is an function used to to calculated some value for given data. As we see check is used to check given data with calculated sum. Data may be little or very big like 1 MB, 10 MB etc. but the checksum value will be the same size bu different for each different type of data. checksum is also called hash values. Checksum Algorithms There are a lot of algorithms used to...

How To Check Integrity Of Files In Linux?

In today IT world everything connected and a lot of data in being downloaded from internet or over networks. This may create some minor problems. The data downloaded may be corrupted or there may be some intruders in network and with man of the middle attack may change our files. There are different solutions for this but simplest and fastest solution is using hash algorithms to verify file integrity. There...
