Package Exports
- hasha
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hasha) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Get the hash of a buffer/string/stream/file
Convenience wrapper around the core crypto module with good defaults.
Install
$ npm install --save hashaUsage
var hasha = require('hasha');
hasha(new Buffer('unicorn'));
//=> 'e233b19aabc7d5e53826fb734d1222f1f0444c3a3fc67ff4af370a66e7cadd2cb24009f1bc86f0bed12ca5fcb226145ad10fc5f650f6ef0959f8aadc5a594b27'
process.stdin.pipe(hasha.stream()).pipe(process.stdout);
hasha.fromFile('unicorn.png', {algorithm: 'md5'}, function (err, hash) {
console.log(hash);
//=> '1abcb33beeb811dca15f0ac3e47b88d9'
});API
See the Node.js crypto docs for more about hashing.
hasha(input, [options])
input
Required
Type: buffer, string
Buffer you want to hash.
While strings are supported you should prefer buffers as they're faster to hash.
hasha.stream([options])
Returns a hash transform stream.
hasha.fromStream(input, [options], callback)
input
Required
Type: stream
callback(error, hash)
hasha.fromFile(input, [options], callback)
input
Required
Type: string
Path to the file to hash.
callback(error, hash)
hasha.fromFileSync(input, [options])
Returns the hash.
input
Required
Type: string
Path to the file to hash.
Options
encoding
Type: string
Default: hex
Values: hex, base64, buffer, binary
Encoding of the returned hash.
algorithm
Type: string
Default: sha512
Values: md5, sha1, sha256, sha512, etc (platform dependent)
The md5 algorithm is good for file revving, but you should never use md5 or sha1 for anything else. They're insecure.
CLI
$ npm install --global hasha$ hasha --help
Usage
$ hasha <text>
$ cat <file> | hasha
Example
$ hasha unicorn --algorithm=md5
1abcb33beeb811dca15f0ac3e47b88d9
Options
--algorithm Cipher algorithm: md5,sha1,sha256,sha512 Default: sha512s
--encoding Output encoding: hex,base64,buffer,binary Default: hexLicense
