Version 7.1.0keyboard_arrow_down
An interface for CRC32C hashing and validation
Package
@google-cloud/storage
Properties
toString
A method returning the CRC32C as a base64-encoded string.
Example
Hashing the string 'data' should return 'rth90Q=='
js
const buffer = Buffer . from ( 'data' );
crc32c . update ( buffer );
crc32c . toString (); // 'rth90Q=='
update
update : ( data : Buffer ) = > void ;
A method for passing Buffer
s for CRC32C generation.
Example
Hashing buffers from 'some ' and 'text\n'
js
const buffer1 = Buffer . from ( 'some ' );
crc32c . update ( buffer1 );
const buffer2 = Buffer . from ( 'text\n' );
crc32c . update ( buffer2 );
crc32c . toString (); // 'DkjKuA=='
validate
validate : ( value : string ) = > boolean ;
A method validating a base64-encoded CRC32C string.
Example
Should return true
if the value matches, false
otherwise
js
const buffer = Buffer . from ( 'data' );
crc32c . update ( buffer );
crc32c . validate ( 'DkjKuA==' ); // false
crc32c . validate ( 'rth90Q==' ); // true
