hash-file
NPM module that compute a file hash from a JavaScript file handler. It provides also some callback function in order to provide user feedbacks.
Usage
defaultCallbackFinal = function(hash, duration, fileSize, chunkTotal, chunkReorder) {
console.log('Computed hash: ' + hash + ' in ' + duration + 'seconds (#chunks: ' + chunkTotal + ', #reorder: ' + chunkReorder + '). File size: ' + HashFile.humanFileSize(fileSize));
}
defaultCallbackProgress = function(percentage, duration, treatedSize, fileSize, chunkTotal, chunkReorder) {
console.log('File hash in progress ' + percentage + '% after ' + duration + ' seconds (' + HashFile.humanFileSize(treatedSize) + '/' + HashFile.humanFileSize(fileSize) + ') (#chunks: ' + chunkTotal + ', #reorder: ' + chunkReorder + ')');
}
new HashFile(file, callbackHashFinal, callbackHashProgress, this, 'sha1');
Parameters:
-
file
: File object -
callbackHashFinal
: callback function called when the hash is available -
callbackHashProgress
: callback function called when a file's chunk has been treated -
this
: callback function's context -
'sha1'
: CryptoJS hash algorithm- Available algorithms: md5, sha1, sha256, sha512, sha3, ripemd160
