public class DocumentProcessor

Class describes all operations available on a document.

Methods

signDocument

public static void signDocument(InputStream documentStream, PrivateKey privateKey, Certificate certificate, Map<String, Object> options, OutputStream signedDocumentStream)

Signs a document. The sign options are provided by the options parameter. It must be a Map object with the following fields:

  • DOCUMENT_SIGNATURE_FORMAT_KEY: Format to use for signature, given as a string. It can take following value:

    • DOCUMENT_SIGNATURE_FORMAT_PKCS7 for PKCS#7 signature

  • DOCUMENT_HASH_ALGORITHM_KEY: Hash algorithm to use, given as a string. It can take the following values:

    • DOCUMENT_HASH_ALGORITHM_SHA1 for SHA-1 algorithm

    • DOCUMENT_HASH_ALGORITHM_SHA256 for SHA-256 algorithm

    • DOCUMENT_HASH_ALGORITHM_SHA384 for SHA-384 algorithm

    • DOCUMENT_HASH_ALGORITHM_SHA512 for SHA-512 algorithm

Note that this parameter may evolve in the future to handle more options.

Parameters:

  • documentStream – The document to sign, given in an InputStream object.

  • privateKey – A PrivateKey object with private attribute, which will be used to sign the document.

  • certificate – A Certificate object corresponding to a certificate linked to the current private key, with correct signature usages.

  • options – A Map as described above.

  • signedDocumentStream – An OutputStream where the signed document will be written.
