ISNetworks S/MIME
Although our Java S/MIME library is no longer officially supported, we have released it under the Apache license to make it available
to the public. The download includes the full source code, pre-compiled binaries, JavaDoc for the API and examples of how to use the library.
If you are interested in hosting an open source project for the source code, please let us know.
Features
- Sends signed and encrypted messages
- Validates and decrypts messages
- Pure Java
- Works with JDK 1.2.2, 1.3.x, 1.4.x, and 1.5.x
- Adds S/MIME capability to JavaMailTM
1.1.3, 1.2, or 1.3
Frequently Asked Questions
- How can I use certificates
I already have from Verisign, Thawte, etc?
If you only need to use the public key (for verifying a signature
or sending an encrypted message), you can export your DER encoded certificate
to a file and use the CertificateFactory API in the java.security.cert
package to load it.
However, if you need to use your private key to sign or decrypt messages,
the easiest way to use your own certificates is to export both the certificate
and private key in PKCS#12 format and load them from the file through
the KeyStore API in the java.security package. These files will normally
have .p12 or .pfx extensions. The ISNetworks JCE Provider included in
the S/MIME download now includes read-only support for PKCS#12 files,
with some restrictions as documented in the release notes.
Sun also provides a PKCS#12 KeyStore implementation with the Java
Secure Socket Extension (JSSE), but it does not work with all PKCS#12
files.
- What MIME types does
the library support?
Currently, the library
supports the following:
application/pkcs7-mime
(signed-data, enveloped-data, and compressed-data)
application/x-pkcs7-mime (signed-data, enveloped-data, and compressed-data)
multipart/signed
application/pkcs7-signature
application/x-pkcs7-signature
When creating messages,
the library defaults to use the older "x-" prefix when available
for backwards compatibilty with older mail clients. This behavior can
easily be overriden.
What email clients
has the library been tested with?
The library has been
tested against Netscape Messenger 4.77, Microsoft Outlook 2000, and
Microsoft Outlook Express 5 and 6, and Mozilla Mail 1.x.
