P7S Signer (PKCS#7 Format)
P7S Signer is a standards-based electronic signature solution based on PKCS#7 format. Signing electronic documents with P7S Signer will immediately reduce costs, increase security and help organizations comply with regulations. Electronic signatures are based on standard PKI technology, guaranteeing signer authenticity, data integrity and the non-repudiation of electronic documents.
Using P7S Signer you can quickly sign multiple files (any type of files) in PKCS#7 format by selecting input and output directory. This is ideal for bulk signing of large number of corporate files. The files digitally signed with P7S Signer has the p7s or p7m extension and are saved in PKCS#7 format.
Interoperability – The files digitally signed with P7S Signer has the p7s or p7m extension and is (mime-type) application/pkcs7-signed-data type. Details about the standard regarding the creation of such structures are published on RFC 3369, standard initiated by RSA Security Data Inc.
PKI Interoperability – P7S Signer is completely PKI neutral and will work with PKI components from any vendor (this includes CAs, certificates, CRLs, smartcards, etc.). P7S Signer signatures are compatible PKCS#7 – Cryptographic Message Syntax Standard.
Timestamping - Like signatures, timestamps are easier to verify when they’re associated with a timestamp authority’s trusted certificate. Including a timestamp helps to prove that the document wasn’t changed after you had signed it and it reduces the chances of an invalid signature.
Long-term validation purposes - Using our software you can sign and timestamp documents for long-term validation purposes. P7S Signer supports digital signatures which include embedded RFC 3161 compliant secure timestamps. Such signatures can be verified even after the signer’s certificate expires or is revoked.
SHA256/512 and RSA 2048 - Our software can sign documents using SHA256/512 and RSA 2048 or higher key length.
Standard Compliance – P7S Signer signatures are compatible PKCS#7 – Cryptographic Message Syntax Standard.
