  • How and when can the authenticity of the electronic BOE be guaranteed?

    To guarantee the authenticity, integrity and inalterability of the contents of the BOE the electronic edition published on the Agency's website has, since 1 January 2009 included an advanced digital signature.

    Said signature is included separately in each of the provisions published. This ensures the authenticity of a specific provision without having to download the full gazette.

  • ¿Why is a signed electronic document unalterable?

    The process of an electronic signature blocks and "freezes" the content of the document in such a manner that the alteration of same invalidates the electronic signature.

    The electronic signature process is comprised of two operations:

    1. Calculating a summary (or digital hash) of fixed length based on the full content of the document
    2. Encrypting this summary with the private key corresponding to the issuer certificate. The encryption summary is packaged with the document even though the visible content of the document is not encrypted, so it is legible.

    To validated a document signed electronically, that is to confirm that no cause is altered from the signing of the document, three operations must be executed:

    1. Recalculate the (hash) based on the content of the document.
    2. Decipher the hash included in the document using the public key contained in the issuer certificate and
    3. comparing both summaries. If they coincide, document has not been altered since it was signed and, therefore, remains valid. If they do not coincide, there has been an alteration and the signature is declared invalid.

    The method of calculating the summaries of the three properties: (a) the length is always fixed, regardless of the length of the summarised document, (b) a minimum alteration of the content of the document results in a very different summary and (c) calculating a summary is not a systematic operation: one can easily calculate the summary of a text but it is not possible to reconstruct the text based on the summary.

    To validate the pdf documents of the electronic BOE, follow the instructions of the Configuration manual for the validation of the signature (PDF) and install the certificates of the Fábrica Nacional de Moneda y Timbre:

  • What is the CVE?

    Location of the electronic verification code on the PDF pages of the official gazette[D]

    TheCVE, or electronic Verification code consists of a set of characters that uniquely identify the unique the provisions, acts and announcements published in the Official State Gazette.

    This code is printed on each of the pages of each provision, act or announcement published and facilitates access to the original electronic document on the website of the Official State Gazette Agency.

    ¿Why is the CVE important?

    Because any paper copy of the electronic originals of the Official State Gazette, since 1 January 2009, is considered official and authentic if it includes the CVE.

    The CVE allows for the authenticity of any page of the Official State Gazette to be verified in printed form by matching it to the original electronic document. To do so, on the access page to the official gazette you can enter the CVE and obtain the original document, signed electronically, directly from the Agency website.

  • Is there a problem printing the BOE?

    Users with older versions of the program Acrobat Reader (from 5.0 to 7.1) may experience problems printing PDF documents. Specifically, it has been detected that, in some cases, the first page of a provision appears correctly but the following ones only contain the BOE logo.

    There are two solutions to this:

    One solution may be to PRINT the PDF AS AN IMAGE
    1. Update your version of Acrobat Reader to a more recent one. Neither the 8.x versions and the 9.x versions of Acrobat Reader should encounter problems with BOE PDFs. You may do easily from the official Adobe page.
    2. If they cannot or do not wish to update their version of Acrobat Reader, they may opt to select "Print as image", on the "Print/ Advanced Print Setup" of some previous versions of Adobe Acrobat.

    You can find more information on this problem on Adobe's own website.

    Other PDF viewers such as Foxit Reader, PDF-Change Viewer or expert PDF Reader do not experience this problem.
