Basic of Cryptography (Type of Cryptography)- Part II

Cryptography categorized based on number of keys used for encryption and decryption; Below are list of cryptography catgories  Secret Key Cryptography – It is also call symmetric encryption where for both encryption and decryption uses same key. This is mainly used for confidentiality. Public Key Cryptography – It is also called asymmetric encryption; this algorithm uses two key’s one for encryption and one for decryption. … Continue reading Basic of Cryptography (Type of Cryptography)- Part II

SHA-256(Source Code in C#) – Part I

SHA-256 (Secure Hash Algorithm), is one of the cryptographic hash function, commonly used in Blockchain. It generates an almost-unique 256-bit (32-byte) signature for a text.  SHA-256 is successor hash functions to SHA-1. it is one of the strongest hash functions available and has not yet been compromised in any way.   Here is source code written in C#. I will try to give more details in next … Continue reading SHA-256(Source Code in C#) – Part I

Cryptography Hashing

What do you mean by Hashing?

Hashing is process of converting any size of data into fix size of data by performing mathematical operations. A message to be hashed is called input; the Algorithm is used to do so is called hash function; the output is called hash value.   There are many algorithm which used to generate hash value like MD5, SHA-1, SHA-256, Tiger etc.    Hash function generates a … Continue reading What do you mean by Hashing?
