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 this PKI object to its ASN.1 representation.

Returns Asn1BaseBlock
The ASN.1 representation of this object
Overrides PkiBase.toAsn1
- Defined in packages/pki-lite/src/pkcs7/SignerInfo.ts:125

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

verify

verify(
    options: {
        data?: Uint8Array<ArrayBufferLike>;
        publicKeyInfo: SubjectPublicKeyInfo;
    },
): Promise<{ valid: true } | { reasons: string[]; valid: false }>
Parameters
- options: { data?: Uint8Array<ArrayBufferLike>; publicKeyInfo: SubjectPublicKeyInfo }
Returns Promise<{ valid: true } | { reasons: string[]; valid: false }>
- Defined in packages/pki-lite/src/pkcs7/SignerInfo.ts:279

`Static`fromAsn1

fromAsn1(asn1: Asn1BaseBlock): SignerInfo
Creates a SignerInfo from an ASN.1 structure.
Parameters
- asn1: Asn1BaseBlock
  The ASN.1 structure
Returns SignerInfo
A SignerInfo object
- Defined in packages/pki-lite/src/pkcs7/SignerInfo.ts:176

`Static`fromDer

fromDer(derBytes: Uint8Array): SignerInfo
Parameters
- derBytes: Uint8Array
Returns SignerInfo
- Defined in packages/pki-lite/src/pkcs7/SignerInfo.ts:257
