Accessors

pemHeader

get pemHeader(): string
Gets the PEM header name for this object type. Converts the class name to uppercase for use in PEM encoding.

Returns string
Inherited from PkiBase.pemHeader
- Defined in packages/pki-lite/src/core/PkiBase.ts:60

pkiType

get pkiType(): string
Gets the PKI type name for this object (typically the class name). Used for PEM headers and debugging output.

Returns string
Inherited from PkiBase.pkiType
- Defined in packages/pki-lite/src/core/PkiBase.ts:52

Methods

equals

equals(other: PkiBase<any>): boolean
Compares this PKI object with another for equality. Two objects are considered equal if their DER encodings are identical.
Parameters
- other: PkiBase<any>
  The other PKI object to compare with
Returns boolean
true if the objects are equal, false otherwise
Inherited from PkiBase.equals
- Defined in packages/pki-lite/src/core/PkiBase.ts:122

parseAs

parseAs<T>(type: ParseableAsn1<T>): T
Parses this object as a different PKI type. Useful for converting between related PKI structures.
Type Parameters
- T
  The target type to parse as
Parameters
- type: ParseableAsn1<T>
  The target type constructor with parsing capabilities
Returns T
A new instance of the target type
Inherited from PkiBase.parseAs
- Defined in packages/pki-lite/src/core/PkiBase.ts:134

toAsn1

toAsn1(): Asn1BaseBlock
Converts the extension to an ASN.1 structure.

Returns Asn1BaseBlock
Overrides PkiBase.toAsn1
- Defined in packages/pki-lite/src/x509/Extension.ts:69

toDer

toDer(): Uint8Array
Converts this PKI object to DER (Distinguished Encoding Rules) format.

Returns Uint8Array
The DER-encoded bytes of this object
Inherited from PkiBase.toDer
- Defined in packages/pki-lite/src/core/PkiBase.ts:100

toHumanString

toHumanString(): string
Returns a human-readable string representation of this object. By default, returns the same as toString(), but subclasses can override for more user-friendly output.

Returns string
A human-readable string representation
Inherited from PkiBase.toHumanString
- Defined in packages/pki-lite/src/core/PkiBase.ts:90

toJSON

toJSON(): ToJson<T>
Converts this object to a JSON representation.

Returns ToJson<T>
A JSON-serializable representation of this object
Inherited from PkiBase.toJSON
- Defined in packages/pki-lite/src/core/PkiBase.ts:69

toPem

toPem(): string
Converts this PKI object to PEM (Privacy-Enhanced Mail) format.

Returns string
A PEM-encoded string with appropriate headers
Inherited from PkiBase.toPem
- Defined in packages/pki-lite/src/core/PkiBase.ts:109

toString

toString(): string
Returns a string representation of this PKI object. Includes the type name and ASN.1 structure.

Returns string
A string representation for debugging
Inherited from PkiBase.toString
- Defined in packages/pki-lite/src/core/PkiBase.ts:79
