Package io.grafeas.v1beta1.attestation

Class PgpSignedAttestation

  • All Implemented Interfaces:
    com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, PgpSignedAttestationOrBuilder, Serializable
    public final class PgpSignedAttestation
extends com.google.protobuf.GeneratedMessageV3
implements PgpSignedAttestationOrBuilder
     An attestation wrapper with a PGP-compatible signature. This message only
 supports `ATTACHED` signatures, where the payload that is signed is included
 alongside the signature itself in the same file.

      • internalGetFieldAccessorTable

        protected com.google.protobuf.GeneratedMessageV3.FieldAccessorTable internalGetFieldAccessorTable()
        Specified by:
        internalGetFieldAccessorTable in class com.google.protobuf.GeneratedMessageV3

      • getSignature

        public String getSignature()
         Required. The raw content of the signature, as output by GNU Privacy Guard
 (GPG) or equivalent. Since this message only supports attached signatures,
 the payload that was signed must be attached. While the signature format
 supported is dependent on the verification implementation, currently only
 ASCII-armored (`--armor` to gpg), non-clearsigned (`--sign` rather than
 `--clearsign` to gpg) are supported. Concretely, `gpg --sign --armor
 --output=signature.gpg payload.json` will create the signature content
 expected in this field in `signature.gpg` for the `payload.json`
 attestation payload.
        string signature = 1;
        Specified by:
        getSignature in interface PgpSignedAttestationOrBuilder
        Returns:
        The signature.

      • getSignatureBytes

        public com.google.protobuf.ByteString getSignatureBytes()
         Required. The raw content of the signature, as output by GNU Privacy Guard
 (GPG) or equivalent. Since this message only supports attached signatures,
 the payload that was signed must be attached. While the signature format
 supported is dependent on the verification implementation, currently only
 ASCII-armored (`--armor` to gpg), non-clearsigned (`--sign` rather than
 `--clearsign` to gpg) are supported. Concretely, `gpg --sign --armor
 --output=signature.gpg payload.json` will create the signature content
 expected in this field in `signature.gpg` for the `payload.json`
 attestation payload.
        string signature = 1;
        Specified by:
        getSignatureBytes in interface PgpSignedAttestationOrBuilder
        Returns:
        The bytes for signature.

      • getContentTypeValue

        public int getContentTypeValue()
         Type (for example schema) of the attestation payload that was signed.
 The verifier must ensure that the provided type is one that the verifier
 supports, and that the attestation payload is a valid instantiation of that
 type (for example by validating a JSON schema).
        .grafeas.v1beta1.attestation.PgpSignedAttestation.ContentType content_type = 3;
        Specified by:
        getContentTypeValue in interface PgpSignedAttestationOrBuilder
        Returns:
        The enum numeric value on the wire for contentType.

      • getContentType

        public PgpSignedAttestation.ContentType getContentType()
         Type (for example schema) of the attestation payload that was signed.
 The verifier must ensure that the provided type is one that the verifier
 supports, and that the attestation payload is a valid instantiation of that
 type (for example by validating a JSON schema).
        .grafeas.v1beta1.attestation.PgpSignedAttestation.ContentType content_type = 3;
        Specified by:
        getContentType in interface PgpSignedAttestationOrBuilder
        Returns:
        The contentType.

      • getPgpKeyId

        public String getPgpKeyId()
         The cryptographic fingerprint of the key used to generate the signature,
 as output by, e.g. `gpg --list-keys`. This should be the version 4, full
 160-bit fingerprint, expressed as a 40 character hexidecimal string. See
 https://tools.ietf.org/html/rfc4880#section-12.2 for details.
 Implementations may choose to acknowledge "LONG", "SHORT", or other
 abbreviated key IDs, but only the full fingerprint is guaranteed to work.
 In gpg, the full fingerprint can be retrieved from the `fpr` field
 returned when calling --list-keys with --with-colons.  For example:
 ```
 gpg --with-colons --with-fingerprint --force-v4-certs \
     --list-keys attester@example.com
 tru::1:1513631572:0:3:1:5
 pub:...<SNIP>...
 fpr:::::::::24FF6481B76AC91E66A00AC657A93A81EF3AE6FB:
 ```
 Above, the fingerprint is `24FF6481B76AC91E66A00AC657A93A81EF3AE6FB`.
        string pgp_key_id = 2;
        Specified by:
        getPgpKeyId in interface PgpSignedAttestationOrBuilder
        Returns:
        The pgpKeyId.

      • getPgpKeyIdBytes

        public com.google.protobuf.ByteString getPgpKeyIdBytes()
         The cryptographic fingerprint of the key used to generate the signature,
 as output by, e.g. `gpg --list-keys`. This should be the version 4, full
 160-bit fingerprint, expressed as a 40 character hexidecimal string. See
