CreateAttributesMetadata create the AttributesMetadata from the original metadata.
CreateAttributesMetadataFromCert creates the AttributesMetadata from the original metadata and certificate "cert".
CreateAttributesMetadataObjectFromCert creates an AttributesMetadata object from certificate "cert", metadata and the attributes keys.
DecryptAttributeValue decrypts "encryptedValue" using "attributeKey" and return the decrypted value.
EncryptAttributeValue encrypts "attributeValue" using "attributeKey".
EncryptAttributeValuePK0 encrypts "attributeValue" using a key derived from preK0.
GetAttributesMetadata object from the original metadata "metadata".
GetKForAttribute derives the K for the attribute "attributeName" and returns the key.
GetValueForAttribute derives the K for the attribute "attributeName" and returns the value.
ParseAttributesHeader parses a string and returns a map with the attributes.
ReadAttributeHeader read the header of the attributes.
