Functions

decodeAsn1VarBigInt

fun Source<*>.decodeAsn1VarBigInt(): Pair<Asn1Integer, ByteArray>

Decodes an ASN.1 unsigned varint to a Asn1Integer, copying all bytes from the source into a ByteArray.

decodeAsn1VarUInt

fun Source<*>.decodeAsn1VarUInt(): Pair<UInt, ByteArray>

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

decodeAsn1VarULong

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

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

fun <A : Asn1Element, T : Asn1Encodable<A>> Asn1Decodable<A, T>.decodeFromDer(src: Source<*>, limit: Long?, assertTag: Asn1Element.Tag? = null): T

Decodes src as DER using this Asn1Decodable.

fun Asn1Encodable<*>.encodeToDer(sink: Sink)

fun Asn1Element.Companion.parse(source: Source<*>, limit: Long?): Asn1Element

Parses the provided source into a single Asn1Element.

fun Asn1Element.Companion.parseAll(source: Source<*>, limit: Long?): List<Asn1Element>

Parses all ASN.1 elements from source.

fun Asn1Element.Companion.parseFirst(source: Source<*>, limit: Long?): Pair<Asn1Element, Long>

Parses the first ASN.1 element from source.

readAsn1Element

fun Source<*>.readAsn1Element(limit: Long?): Pair<Asn1Element, Long>

Decodes a single Asn1Element from this source.

fun Source<*>.readAsn1Tag(): Asn1Element.Tag

readFullyToAsn1Elements

fun Source<*>.readFullyToAsn1Elements(limit: Long?): Pair<List<Asn1Element>, Long>

Reads all parsable ASN.1 elements from this source.

readTwosComplementInt

fun Source<*>.readTwosComplementInt(nBytes: Int, lenient: Boolean): Int

Consumes exactly nBytes from this source and interprets it as a signed Int

readTwosComplementLong

fun Source<*>.readTwosComplementLong(nBytes: Int, lenient: Boolean): Long

Consumes exactly nBytes from this source and interprets it as a Long.

readTwosComplementUInt

fun Source<*>.readTwosComplementUInt(nBytes: Int, lenient: Boolean): UInt

Consumes exactly nBytes remaining data from this source and interprets it as a UInt

readTwosComplementULong

fun Source<*>.readTwosComplementULong(nBytes: Int, lenient: Boolean): ULong

Consumes exactly nBytes from this source and interprets it as a signed ULong.

inline fun Source<*>.readUByte(): UByte

writeAsn1VarInt

fun Sink.writeAsn1VarInt(number: Asn1Integer): Int

fun Sink.writeAsn1VarInt(number: UInt): Int

fun Sink.writeAsn1VarInt(number: ULong): Int

Encodes this number 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

writeMagnitudeLong

fun Sink.writeMagnitudeLong(number: Long): Int

Encodes a positive Long to a minimum-size unsigned byte array, omitting the leading zero

writeTwosComplementLong

fun Sink.writeTwosComplementLong(number: Long): Int

Writes a signed long using twos-complement encoding using the fewest bytes required

writeTwosComplementUInt

fun Sink.writeTwosComplementUInt(number: UInt): Int

Encodes an unsigned Int to a minimum-size twos-complement byte array

writeTwosComplementULong

fun Sink.writeTwosComplementULong(number: ULong): Int

Encodes an unsigned Long to a minimum-size twos-complement byte array

inline fun Sink.writeUByte(uByte: UByte)
