Structs

AggregatedProof
BlindedMasterSecret	Blinded Master Secret uses by Issuer in credential creation.
BlindedMasterSecretCorrectnessProof
CredentialKeyCorrectnessProof	Proof of Issuer Public Key correctness
CredentialPrimaryPrivateKey	Issuer's "Private Key" used for signing Credential's attributes' values (primary credential)
CredentialPrimaryPublicKey	Issuer's "Public Key" is used to verify the Issuer's signature over the Credential's attributes' values (primary credential).
CredentialPrimaryPublicKeyMetadata	Primary Public Key Metadata required for building of Proof Correctness of Issuer Public Key
CredentialPrivateKey	Issuer Private Key: contains 2 internal parts. One for signing primary credentials and second for signing non-revocation credentials.
CredentialPublicKey	Issuer Public Key contains 2 internal parts. One for signing primary credentials and second for signing non-revocation credentials. These keys are used to proof that credential was issued and doesn’t revoked by this issuer. Issuer keys have global identifier that must be known to all parties.
CredentialRevocationPrivateKey	Revocation Private Key is used for signing Credential.
CredentialRevocationPublicKey	Revocation Public Key is used to verify that credential was'nt revoked by Issuer.
CredentialSchema	A list of attributes a Credential is based on.
CredentialSchemaBuilder	A Builder of Credential Schema.
CredentialSignature	Issuer's signature over Credential attribute values.
CredentialValues	Values of attributes from Credential Schema (must be integers).
CredentialValuesBuilder	A Builder of Credential Values.
InitProof
MasterSecret	Secret key encoded in a credential that is used to prove that prover owns the credential; can be used to prove linkage across credentials. Prover blinds master secret, generating BlindedMasterSecret and MasterSecretBlindingData (blinding factors) and sends the BlindedMasterSecret to Issuer who then encodes it credential creation. The blinding factors are used by Prover for post processing of issued credentials.
MasterSecretBlindingData	Master Secret Blinding Data used by Prover for post processing of credentials received from Issuer. TODO: Should be renamed MasterSecretBlindingFactors

PrimaryProof
Proof	Proof is complex crypto structure created by prover over multiple credentials that allows to prove that prover:
RevocationBlindedMasterSecretData
RevocationKeyPrivate	Revocation Key Private Accumulator primate key.
RevocationKeyPublic	Revocation Key Public Accumulator public key. Must be published together with Accumulator
RevocationRegistry	Revocation Registry contains accumulator. Must be published by Issuer on a tamper-evident and highly available storage Used by prover to prove that a credential hasn't revoked by the issuer
RevocationRegistryDelta	Revocation Registry Delta contains Accumulator changes. Must be applied to Revocation Registry
RevocationTailsGenerator	Generator of Tail's.
SignatureCorrectnessProof
SimpleTailsAccessor	Simple implementation of RevocationTailsAccessor that stores all tails as HashMap.
SubProof
SubProofRequest	“Sub Proof Request” - input to create a Proof for a credential; Contains attributes to be revealed and predicates.
SubProofRequestBuilder	Builder of “Sub Proof Request”.
VerifiableCredential
Witness
WitnessSignature
