DecryptDeepObject recurses over non trivial PDF objects and decrypts all strings encountered.
func DecryptStream ¶
DecryptStream decrypts a stream buffer using RC4 or AES.
func DecryptString ¶
DecryptString decrypts s using RC4 or AES.
func EncryptDeepObject ¶
func EncryptDeepObject(objIn interface{}, objNr, genNr int, key []byte, aes bool) (*types.PDFStringLiteral, error)
EncryptDeepObject recurses over non trivial PDF objects and encrypts all strings encountered.
func EncryptStream ¶
EncryptStream encrypts a stream buffer using RC4 or AES.
func EncryptString ¶
EncryptString encrypts s using RC4 or AES.
func HasNeededPermissions ¶
HasNeededPermissions returns true if permissions for pdfcpu processing are present.
func SupportedCFEntry ¶
SupportedCFEntry returns true if all entries found entries are suppoerted.
func ValidateOwnerPassword ¶
ValidateOwnerPassword validates ownerpw.
func ValidateUserPassword ¶

Types ¶
type Encrypt ¶
type Encrypt struct {
// contains filtered or unexported fields
}
Encrypt wraps around all defined encryption attributes.
func SupportedEncryption ¶
SupportedEncryption returns true if used encryption is supported by pdfcpu.
