  • [Password (256bit V8 or later)]
    Only users who know the password can open or manipulate the document. In this module, the encryption method is stronger than in the [Password (128bit V5 or later)] module.
    Protected documents set in this module cannot be opened in DocuWorks Ver.7.x or earlier.
  • [Password (128bit V5 or later)]
    Only users who know the password can open or manipulate the document. In this module, the encryption method is stronger than in the [Password (V4 compatible)] module.
    Protected documents set in this module cannot be opened in DocuWorks Ver.4.x or earlier.
  • [Password (56bit V4 or later)]
    Only users who know the password can open or manipulate the document.
    Protected documents set in this module can be opened by entering the password even in DocuWorks Ver.4.x.
  • [Digital Certificate (256bit V8 or later)]
    Only users who have the specified certificate issued by Certificate Authority (CA) can open or manipulate the document. You do not need password management such as informing others of them or concealing them, and there is no possibility of being cracked by analogy. You can specify security with public-key cryptosystem using general public-key certificates (digital ID).
    In this module, the encryption method is stronger than in the [Digital Certificate (128bit V5 or later)] module.
    Protected documents set in this module cannot be opened in DocuWorks Ver.7.x or earlier.
  • [Digital Certificate (128bit V5 or later)]
    Only users who have the specified certificate issued by Certificate Authority (CA) can open or manipulate the document. You do not need password management such as informing others of them or concealing them, and there is no possibility of being cracked by analogy. You can specify security with public-key cryptosystem using general public-key certificates (digital ID).
    Protected documents set in this module cannot be opened in DocuWorks Ver.4.x or earlier.
  • [DocuWorks Electronic Signature (128bit V5 or later)]
    Only users who have the specified signature can open or manipulate the document. You can specify security with public-key cryptosystem.
    Protected documents set in this module cannot be opened in DocuWorks Ver.4.x or earlier.
Note
  • DocuWorks Electronic Signature is a unique function to DocuWorks. On the other hand, Digital Certificate is a method using Internet-standard public-key cryptosystem (PKI), and is used in various applications such as encrypted mails with S/MIME, Web access authentication, or VPN. Using the security function with Digital Certificate, you can apply security to DocuWorks documents and use them under the same certificate system as in other PKI applications.
  • To change the security settings of a protected document, use the security module applied to protect the document. To protect the protected document by another security module, cancel the current security settings and then specify new settings.
