Digital Signature of Hash (HMACSHA256) in Java using SHA256 algorithm & Pkcs1 RSA signature padding didn’t match with dot net implementation

I am trying to create digital signature of the hash (created using HMACSHA256) in Java using SHA256 algorithm & Pkcs1 RSA signature padding but it is not producing the same signature as implemented in .net by vendor. My Java code : private String hmacSha256(String data, String key) throws Exception { Mac mac = Mac.getInstance(“HmacSHA256”); SecretKeySpec […]

Guide to Hash Tables in Python

While Python doesn’t have a built-in data structure explicitly called a “hash table”, it provides the dictionary, which is a form of a hash table. Python dictionaries are unordered collections of key-value pairs, where the key is unique and holds a corresponding value. Thanks to a process known as “hashing”, dictionaries enable efficient retrieval, addition, […]
