Functions ¶
func BuildAttributesHeader ¶
BuildAttributesHeader builds a header attribute from a map of attribute names and positions.
func CreateAttributesMetadata ¶
func CreateAttributesMetadata(raw []byte, metadata []byte, preK0 []byte, attributeKeys []string) ([]byte, error)
CreateAttributesMetadata create the AttributesMetadata from the original metadata
func CreateAttributesMetadataFromCert ¶
func CreateAttributesMetadataFromCert(cert *x509.Certificate, metadata []byte, preK0 []byte, attributeKeys []string) ([]byte, error)
CreateAttributesMetadataFromCert creates the AttributesMetadata from the original metadata and certificate "cert".
func CreateAttributesMetadataObjectFromCert ¶
func CreateAttributesMetadataObjectFromCert(cert *x509.Certificate, metadata []byte, preK0 []byte, attributeKeys []string) *pb.AttributesMetadata
CreateAttributesMetadataObjectFromCert creates an AttributesMetadata object from certificate "cert", metadata and the attributes keys.
func DecryptAttributeValue ¶
DecryptAttributeValue decrypts "encryptedValue" using "attributeKey" and return the decrypted value.
func EncryptAttributeValue ¶
EncryptAttributeValue encrypts "attributeValue" using "attributeKey"
func EncryptAttributeValuePK0 ¶
func EncryptAttributeValuePK0(preK0 []byte, attributeName string, attributeValue []byte) ([]byte, error)
EncryptAttributeValuePK0 encrypts "attributeValue" using a key derived from preK0.
func GetAttributesMetadata ¶
func GetAttributesMetadata(metadata []byte) (*pb.AttributesMetadata, error)
GetAttributesMetadata object from the original metadata "metadata".
func GetKForAttribute ¶
GetKForAttribute derives the K for the attribute "attributeName" and returns the key
func GetValueForAttribute ¶
func GetValueForAttribute(attributeName string, preK0 []byte, cert *x509.Certificate) ([]byte, error)
GetValueForAttribute derives the K for the attribute "attributeName" and returns the value
func ParseAttributesHeader ¶
ParseAttributesHeader parses a string and returns a map with the attributes.
func ReadAttributeHeader ¶
ReadAttributeHeader read the header of the attributes.
