In the previous CryptoCode series articles, I had written about generating MD5/SHA1/SHA256 hashes, encryption/decryption algorithms using Windows Cryptography functions. Today I am writing about creating SHA256 hash using OpenSSL’s Cryptography Library. OpenSSL is very popular library providing SSL & Cryptography based functions which is consumed by top softwares. OpenSSL library is FREE to use in […]

Recently I had been writing about code samples for demonstrating the usage of various Cryptography functions such as generating MD5/SHA256 hash generation, encryption of password based on the key, BASE 64 encoder/decoder etc. Here is the index of all those Crypto articles and associated tools. . Crypto Articles CryptoCode: Generate MD5 Hash using Windows Cryptography […]

In previous posts I had written about Base64 decoder and other hashing algorithms using Windows Cryptography functions.  In this post I will write simple C program for BASE64 Encoder. . Due to its simplicity BASE64 has become very popular choice for  simple encoding of the passwords or other sensitive data.  But due to its trivial […]

In previous blog posts I had written about MD5 & SHA256 Hash generation algorithms as well as DES Encryption/Decryption methods using Windows Cryptography Functions.  Today I am going to present a crypto program for Base64 Decoder – very popular encoding algorithm. . Base64 is commonly used along side the encryption/decryption algorithms as a double layer […]

In previous posts, I wrote example code for generating MD5 Hash & SHA1 Hash using Windows Cryptography Functions. Here I am going to write about DES encryption/decryption algorithm with SHA1 based Hash key generated using Password.  This is most common way of generating password where in unique data is used to generate a Hash Key […]

In my previous blog post on ‘Generating MD5 Hash’,  I wrote code example on creating MD5 hash.  Today I will be presenting the direct code sample for generating SHA1 hash using Windows Cryptography functions. Due to various collision problems with MD5 Hash, now a days SHA256 hash is used more extensively for unique identification. The […]

Here I have decided to put together series of Crypto sample using Windows Cryptography functions as well as OpenSSL library. This is to make it easier for myself as well as others to find ready to use cryptography code examples. Though some of these code samples are present some where on the net, I am […]
