Functions ¶
func HMAC512Split ¶
HMAC512Split computes an HMAC using SHA512 for a given key and seed, splitting the digest into left and right byte slices.
func HexChecksumDecode ¶
HexChecksumDecode decodes a hexidecimal string, verifies the 4 byte checksum and returns the decoded byte slice.
func HexChecksumEncode ¶
HexChecksumEncode appends a 4 byte SHA256d checksum to the byte slice and returns the hexidecimal encoding.
func OrSlice ¶
OrSlice takes the cumulative OR of all bytes in a byte slice. This method is useful for determining whether or not a byte slice has been zeroed.
func PaddedCopy ¶
Copies at most size bytes from src to dst, offset by the difference between size and len(src).
