Questions about the calculation results of CRC32.buf and CRC32.str

[adonis-lsh]

/* Frequently faster in NodeJS */
crc32 = CRC32.buf(Buffer.from(bstr, "binary"), 0);
crc32 = CRC32.str(bstr, 0);

Whether the calculation result of CRC32.buf in the node and the calculation result of CRC32.str in the scheduler are always the same with the same parameters?I want to use one on the server and one on the browser, but I'm afraid that the two methods will calculate the same string inconsistently.
