ASN1Integer class

ASN1Integer encoding / decoding.

Note that asn1 integers can be arbitrary precision, so a BigInt is used to hold the int value. Convenience methods are provided to deal with int or BigInt

Constructors

ASN1Integer(BigInt valueAsBigInteger, {int tag = INTEGER_TYPE})
ASN1Integer.fromBytes(Uint8List bytes)
ASN1Integer.fromInt(int x, {int tag = INTEGER_TYPE})

Properties

encodedBytes → Uint8List
Get the encoded byte representation for this object. This can trigger calling the subclasss _encode method if the object has not yet been encoded
no setterinherited
extendedTag → int?
no setterinherited
hasExtendedTag → bool
no setterinherited
hashCode → int
The hash code for this object.
no setteroverride
intValue → int
no setter
isEncoded → bool
Check if the encoding is ready.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
tag → int
The BER tag representing this object

totalEncodedByteLength → int
The total length of this object in bytes - including its value bytes and the encoded tag and length bytes.

Methods

contentBytes() → Uint8List
Returns the real content of a tag. This might be equal to valueBytes for some tags.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toHexString() → String
inherited
toString() → String
A string representation of this object.
override
valueBytes() → Uint8List
Return just the value bytes.

Operators

operator ==(Object other) → bool
The equality operator.
override

Static Methods

decodeBigInt(Uint8List bytes) → BigInt
Given an ASN1 encoded integer return the integer value of the byte stream.
decodeInt(Uint8List bytes) → int
encodeBigInt(BigInt number) → Uint8List
encodeInt(int x) → Uint8List
