Software AG, Inc. announced the availability of a new software component for its Tamino XML Server 4.1 that allows the native XML server to validate digital signatures in support of secure electronic communications. Tamino XML Security Extensions makes the completion of legally binding contracts and other sensitive transactions over the Internet more secure and convenient. Digital signature technology allows the author of an electronic document to digitally “sign” the document and check later to see if the document has been modified without permission. Tamino XML Security Extensions automatically checks whether an electronic document has been given a digital signature, and verifies the validity of the signature during the database storage transaction for the signed document. A Developer Community download for Tamino XML Security Extensions is available.
