Are you really sure PKCS#7 supports encrypting of data without a certificate ? I know it was designed as a successor for PEM, which supports encrypting with symetric keys, but if PKCS#7 supports it, I don't know. But I'm almost sure that if you use PKCS#7 with public keys, you need a certificate. > I have searched but I do not find anything to do it. It may be possible that PKCS#7 does not support encrypting without a certificate. It also may be possible that OpenSSL does only support PKCS#7 with certificates. > I work with c, and the function PKCS7_encrypt() needs > certificates...There is some another function that generates pkcs7 > format without need of certificates? > > If this isn't possible..., there is another PKCS format that allows to > cipher any type of data only with a password? (PKCS5,PKCS11,PKCS12...) PKCS#11 defines the interface to hardware modules but not a file format. PKCS#12 is used to store private keys and their certificates in a file. It may be possible to use it to encrypt other data. But there is no (higher level) interface to do it. You could use other encryption formats. OpenPGP comes to mind.
