DEREncoder

Overview

DEREncoder is a class in Aspose.Pdf FOSS for Java.

Encodes ASN.1 DER (Distinguished Encoding Rules) structures.

Signature	Description
`encodeSequence()` → `byte[]`	Encodes a SEQUENCE (tag 0x30) containing the given contents.
`encodeSet()` → `byte[]`	Encodes a SET (tag 0x31) containing the given contents.
`encodeOID(oid: String)` → `byte[]`	Encodes an OID from dotted string.
`encodeInteger(value: BigInteger)` → `byte[]`	Encodes an INTEGER.
`encodeInteger(value: int)` → `byte[]`	Encodes a small integer.
`encodeOctetString(data: byte[])` → `byte[]`	Encodes an OCTET STRING.
`encodeBitString(data: byte[])` → `byte[]`	Encodes a BIT STRING (with unused-bits prefix byte 0x00).
`encodeNull()` → `byte[]`	Encodes NULL.
`encodeContextTag(tagNumber: int, content: byte[])` → `byte[]`	Encodes a context-specific constructed tag [n] EXPLICIT.
`encodeContextTagImplicit(tagNumber: int, content: byte[])` → `byte[]`	Encodes a context-specific implicit tag [n] IMPLICIT (preserves inner content).
`encodeUTCTime(date: Date)` → `byte[]`	Encodes a UTCTime value.
`encodePrintableString(s: String)` → `byte[]`	Encodes a PrintableString.
`encodeUTF8String(s: String)` → `byte[]`	Encodes a UTF8String.
`encodeAlgorithmIdentifier(oid: String)` → `byte[]`	Encodes an AlgorithmIdentifier SEQUENCE { OID, NULL }.
`encodeTLV(tag: int, value: byte[])` → `byte[]`	Encodes a Tag-Length-Value triple.
`encodeLength(length: int)` → `byte[]`	Encodes a DER length value.
