Compatible Software - DigiStamp Partners and Software testing

Timestamps are great, but they are even better when combined with more holistic partner solutions. In the section below we provide a description of how our time stamps are combined with other software. Thanks to these partners and software our customers can benefit from these new technologies and the cost-savings of using auditable timestamps in their existing systems.

If you know of other solutions or would like assistance with testing then please contact our support team.

	Adobe
			Adobe Acrobat 7 and later include digital timestamp functionality, which is provided by an Adobe-supplied signature framework. DigiStamp provides the Internet based time-stamp server to create the third-party time stamp. Additional information is available here.

	IBM
			In 1999, an agreement was made with IBM to customize their secure hardware to create trusted time stamps bases upon the RFC 3161 standard. Additional information is available here.

	ARX
			CoSign supports access to DigiStamp's Internet based time stamp servers. Details are here. The CoSign digital signature solution supports all major applications and file formats (Word, Excel®, Outlook®, PDF®, TIFF, AutoCAD®, InfoPath® and many more). See arx.com

	E-Lock
			E-Lock ProSigner and DeskSeal Web support using DigiStamp's Internet based time stamp servers. ProSigner supports the third party application like MS Word, Excel, Adobe Acrobat and allows user to sign documents within these applications. See elock.com
	RSA Security
	.		Our SecureTime Java toolkit was tested by RSA to support to the RSA Certificate Manager software. The integration testing was for the CA authority function for process certificate revocation lists. Additional information is available here.

	more options		These options require programming

	Bouncy Castle		An example of using bouncycastle java tools comes with our Java toolkit. Our example uses DigiStamp code only for the communication step to provide automatic failover between our two sites. Additional information is available here.

	OpenSSL		OpenSSL supports RFC3161 timestamps a can be used to create a time stamp request and verifying the DigiStamp timestamp.

	S/MIME Library		This testing was done by one of our customers. The The S/MIME Freeware Library (SFL) is available here

	OpenTSA		We have not been able to resolve the problem of using OpenTSA with HTTP authentication. Our time stamp servers authenticate the user with their user ID and password. An alternative is to use the DigiStamp Gateway because it does not require client authentication.

	Oracle timestamp in PKI SDK		This testing was done by one of our customers. In the Oracle documentation see the class HttpTSPRequest for support of RFC 3161 time stamps.

	Office 2010 timestamp	X	We are not able to support Microsoft Office timestamps because: Office does not provide the function to "authenticate" the client to the TSA Server; for example, there is no place to enter the account number and password (as of 2011-01)

	Microsoft Authenticode	X	We do not support Authenticode timestamps; they are a unique format used in Microsoft code signing. The timestamps from DigiStamp are in a different PKI / IETF format that was as part of digital signature standards.

Both technology and legal factors make e-TimeStamp an effective tool. An essential ingredient of e-TimeStamp is that we are the trusted third-party. e-TimeStamp uses a digital signature. A digital signature is a legal signature based on the technology of encryption. Below is additional reading on these subjects.
