Interface CRC32CValidator (7.16.0)

An interface for CRC32C hashing and validation

Package

toString:()=>string;

A method returning the CRC32C as a base64-encoded string.

Example

Hashing the string 'data' should return 'rth90Q=='

jsconstbuffer=Buffer.from('data');crc32c.update(buffer);crc32c.toString();// 'rth90Q=='

update:(data:Buffer)=>void;

A method for passingBuffers for CRC32C generation.

Example

Hashing buffers from 'some ' and 'text\n'

jsconstbuffer1=Buffer.from('some ');crc32c.update(buffer1);constbuffer2=Buffer.from('text\n');crc32c.update(buffer2);crc32c.toString();// 'DkjKuA=='

validate:(value:string)=>boolean;

A method validating a base64-encoded CRC32C string.

Example

Should returntrue if the value matches,false otherwise

jsconstbuffer=Buffer.from('data');crc32c.update(buffer);crc32c.validate('DkjKuA==');// falsecrc32c.validate('rth90Q==');// true
