DEFAULT_SIG_SUBFILTER = SigSeedSubFilter.ADOBE_PKCS7_DETACHED ĭefault SubFilter to use for a PDF signature. DEFAULT_MD = 'sha256' ĭefault message digest algorithm used when computing digests for use in This module defines constants & defaults used by pyHanko when creating digital Write the output to the specified output stream. Size of the internal buffer (in bytes) used to feed data to the messageĭigest function if the input stream does not support memoryview. Object, or output if the latter is not None. This is also the message digest algorithm that should appear in theĬorresponding signerInfo entry in the CMS object that ends upīeing embedded in the signature field. text_params : Optional = None Īdditional text interpolation parameters to pass to the underlying Signer name to show in the signature appearance. Timestamp to show in the signature appearance. Stamp style to use to generate the appearance. Part of the low-level PdfCMSEmbedder API, see SigAppearanceSetup ( style : BaseStampStyle, timestamp : datetime, name : Optional, text_params : Optional = None ) Optional appearance settings, see SigAppearanceSetup. Optional DocMDP settings, see SigMDPSetup. In particular, this determines the number of bytes to allocate for theĬMS object. sig_placeholder : PdfSignedData īare-bones placeholder object, usually of type SignatureObject SigObjSetup ( sig_placeholder : PdfSignedData, mdp_setup : Optional = None, appearance_setup : Optional = None ) ĭescribes the signature dictionary to be embedded as the form field’s value. The coroutine’s final yield is the value of the signatureĭictionary’s /Contents entry, given as a hexadecimal string. The CMS object can be supplied as a rawīytes object, or an asn1crypto-style object. The IncrementalPdfFileWriter currently in use.įinally, the caller should pass in a CMS object to place inside Output is the output stream to which the document to beįrom this point onwards, no objects may be changed or added to Prepared_digest is a PreparedByteRangeDigest objectĬontaining the document digest and the relevant offsets, and
It will then yield a prepared_digest, output tuple, where Placeholder region reserved for the signature and compute theĭocument’s hash and yield it to the caller. The coroutine will write the entire document with a Next, the caller should send a SigIOSetup object,ĭescribing how the resulting document should be hashed and written For convenience, theĬoroutine will then yield a reference to the signature dictionary Is subsequently processed by the coroutine. The caller should then send in a SigObjSetup object, which The coroutine follows the following specific protocol.įirst, it retrieves or creates the signature field to embed theĬMS object in, and yields a reference to said field. Implementation to handle the cryptographic operations if necessary. In almost every other case, you’re better of using Where the construction of the CMS object to be embedded This is a very low-level interface that performs virtually noĮrror checking, and is intended to be used in situations
