encrypting in java, decrypting in VB

Hi,

I need some Visual Basic component that allows me to decrypt text and
files encrypted with java through the JCE API. I've searched the WWW
looking for some activex control or dll, but I found that they are
terribly undocumented and I don't know what are exactly their
assumptions about encripted data.

Any help will be greatly appreciated.

TIA
Gabriel

Try CAPICOM component.
This old com component wraps a lot of
Windows CryptoAPI: probably you can
found what you need.

Go to http://msdn.microsoft.com and search for CAPICOM
download.

An alternative way is to search it with www.google.com.

If you use standard format (pkcs7: *.p7m and *.p7s files)
you will be able encrypt/decrypt from java to vb and viceversa.

Have good luck!

Bye,

And what about components that calculate hash functions like MD5 or
SHA-1, or MACs like HMAC?

Does anybody knows of some that are compatible with Java JCE? That is,
calculating a digest in java and saving it to a file, then taking the
same calculation from a visual basic application and compare the new
digest with that of the file.

TIA

If you use standard files (pkcs*), don't care about compatibility.
