JSSHA256 offers a compact JavaScript interpretation of the reliable SHA256 secure hash function.
One of the standout features of jssha256 is its simplicity. Using just a few lines of code, I was able to easily compute the SHA256 hash value of a string like 'abc'. Here's an example:
SHA256_init();
SHA256_write("abc");
digest = SHA256_finalize();
digest_hex = array_to_hex_string(digest);
Using the shortcut function SHA256_hash, I was able to achieve the same result even more quickly:
digest_hex = SHA256_hash("abc");
In addition to SHA256, jssha256 also includes support for HMAC calculation. This proved to be just as easy to use as the SHA256 functionality. Here's an example of computing the HMAC of the string 'abc' using the key 'secret key':
HMAC_SHA256_init("secret key");
HMAC_SHA256_write("abc");
mac = HMAC_SHA256_finalize();
mac_hex = array_to_hex_string(mac);
As with SHA256, there's a convenient shortcut function available for computing the HMAC as well:
mac_hex = HMAC_SHA256_MAC("secret key", "abc");
Overall, I found jssha256 to be a reliable and easy-to-use tool for working with secure hash functions and HMAC computation in JavaScript. Highly recommended!
