ASN1 frequently embeds data in the contents of octet strings and bit strings. asn1parse doesn't actually attempt to parse these things unless you tell it to with the -strparse function. In this case you can use the 'smime' command to extract content, for example: openssl smime -verify -inform PEM -in file.pem -noverify -out content.der 'content.der' seems to be a PKCS#7 envelopedData structure which you can process further with another 'smime' command if you happen to have the appropriate certificate and private key of the recipient.
