I've a problem. I need to cypher a buffer of bytes with pkcs7 format but
I can't use certificates,i need encrypt using only a key or password.
I have searched but I do not find anything to do it.
Read the syntax for PKCS#7:
ftp://ftp.rsasecurity.com/pub/pkcs/ascii/pkcs-7.asc
For enveloped data:
EnvelopedData ::= SEQUENCE {
version Version,
recipientInfos RecipientInfos,
encryptedContentInfo EncryptedContentInfo }
where
RecipientInfos ::= SET OF RecipientInfo
and
RecipientInfo ::= SEQUENCE {
version Version,
issuerAndSerialNumber IssuerAndSerialNumber,
keyEncryptionAlgorithm
KeyEncryptionAlgorithmIdentifier,
encryptedKey EncryptedKey }
Obviously for signed and enveloped data the sender needs a
cert, too.
