sha1-browser

A fork of sha1 package which removes reference of Buffer that may trigger webpack NodeSourcePlugin and enlarge your bundle size.

Input with Buffer type is not available.

sha1

a native js function for hashing messages with the SHA-1 algorithm

Installation

npm install sha1

ender build sha1

Example

var sha1 = require('sha1');

sha1("message");

This will return the string:

"6f9b9af3cd6e8b8a73c2cdced37fe9f59226e27d"

API

sha1(msg)

Returns the SHA-1 hash of the given message.

msg String -- the message that you want to hash.

It's as simple as that.

sha1(msg, options)

Returns the binary string or bytes array representation of SHA-1 hash for msg, based on options. There are two mutually exclusive option flags:

asString true -- return binary string from digest bytes
asBytes true -- return array of digest bytes

with empty options object, default output is hex-encoded string of digest bytes.

Examples

The following examples demonstate three possible outputs formats.

Get bytes array and put into buffer (straightforward):

var hash_bytes = sha1("message", {asBytes: true});
var result = new Buffer(hash_bytes);

Get binary string and decode into buffer as digest bytes:

var hash_binary = sha1("message", {asString: true});
var result = new Buffer(hash_binary, 'binary');

Get default hex-encoded output and decode into buffer as digest bytes:

var hash_text = sha1("message", {});
var result = new Buffer(hash_text, 'hex');
