Functions

func NewAdobeECCDetached

func NewAdobeECCDetached(privateKey *ecdsa.PrivateKey, certificate *x509.Certificate) (model.SignatureHandler, error)

NewAdobeECCDetached creates a new Adobe.PPKMS/Adobe.PPKLite adbe.ECC.detached signature handler. Both parameters may be nil for the signature validation.

func NewAdobePKCS7Detached

func NewAdobePKCS7Detached(privateKey *rsa.PrivateKey, certificate *x509.Certificate) (model.SignatureHandler, error)

NewAdobePKCS7Detached creates a new Adobe.PPKMS/Adobe.PPKLite adbe.pkcs7.detached signature handler. Both parameters may be nil for the signature validation.

func NewAdobeX509RSASHA1

func NewAdobeX509RSASHA1(privateKey *rsa.PrivateKey, certificate *x509.Certificate) (model.SignatureHandler, error)

NewAdobeX509RSASHA1 creates a new Adobe.PPKMS/Adobe.PPKLite adbe.x509.rsa_sha1 signature handler. Both parameters may be nil for the signature validation.

func NewAdobeX509RSASHA1Custom

func NewAdobeX509RSASHA1Custom(certificate *x509.Certificate, signFunc SignFunc) (model.SignatureHandler, error)

NewAdobeX509RSASHA1Custom creates a new Adobe.PPKMS/Adobe.PPKLite adbe.x509.rsa_sha1 signature handler with a custom signing function. Both parameters may be nil for the signature validation.

func NewEmptyAdobeECCDetached

func NewEmptyAdobeECCDetached(signatureLen int) (model.SignatureHandler, error)

NewEmptyAdobePKCS7Detached creates a new Adobe.PPKMS/Adobe.PPKLite adbe.pkcs7.detached signature handler. The generated signature is empty and of size signatureLen. The signatureLen parameter can be 0 for the signature validation.

func NewEmptyAdobePKCS7Detached

func NewEmptyAdobePKCS7Detached(signatureLen int) (model.SignatureHandler, error)

NewEmptyAdobePKCS7Detached creates a new Adobe.PPKMS/Adobe.PPKLite adbe.pkcs7.detached signature handler. The generated signature is empty and of size signatureLen. The signatureLen parameter can be 0 for the signature validation.
