Now that the crc32c() library function directly takes advantage of architecture-specific optimizations, it is unnecessary to go through the crypto API. Just use crc32c(). This is much simpler, and it improves performance due to eliminating the crypto API overhead. Signed-off-by: Eric Biggers...

Unconventional for a CRC32 checksum, this library uses signed 32-bit integers. This is for performance reasons. Standard JS operators can convert between signed and unsigned 32-bit integers: CRC32.str("SheetJS")// -1647298270 (signed)CRC32.str("SheetJS")>>>0// 2647669026 (unsigned)(CRC32.st...
