decodeAsn1VarULong

fun ByteArray.decodeAsn1VarULong(): Pair<ULong, ByteArray>(source)

Decodes an ULong from bytes using varint encoding as used within ASN.1: groups of seven bits are encoded into a byte, while the highest bit indicates if more bytes are to come. Trailing bytes are ignored.

Return

the decoded ULong and the underlying varint-encoded bytes as ByteArray

Throws

if the number is larger than ULong.MAX_VALUE

fun Source.decodeAsn1VarULong(): Pair<ULong, ByteArray>(source)

Decodes an ASN.1 unsigned varint to an ULong, copying all bytes from the source into a ByteArray.

Return

the decoded ULong and the underlying varint-encoded bytes as ByteArray

Throws

if the number is larger than ULong.MAX_VALUE
