|
|
* The ASN.1 representation of PKCS#7 is as follows
|
|
* (see RFC #2315 for details, http://www.ietf.org/rfc/rfc2315.txt):
|
|
*
|
|
* A PKCS#7 message consists of a ContentInfo on root level, which may
|
|
* contain any number of further ContentInfo nested into it.
|
|
*
|
|
* ContentInfo ::= SEQUENCE {
|
|
* contentType ContentType,
|
|
* content [0] EXPLICIT ANY DEFINED BY contentType OPTIONAL
|
|
* }
|
|
*
|
|
* ContentType ::= OBJECT IDENTIFIER
|
|
*
|
|
* EnvelopedData ::= SEQUENCE {
|
|
* version Version,
|
|
* recipientInfos RecipientInfos,
|
|
* encryptedContentInfo EncryptedContentInfo
|
|
* }
|
|
*
|
|
* EncryptedData ::= SEQUENCE {
|
|
* version Version,
|
|
* encryptedContentInfo EncryptedContentInfo
|
|
* }
|
|
*
|
|
* id-signedData OBJECT IDENTIFIER ::= { iso(1) member-body(2)
|
|
* us(840) rsadsi(113549) pkcs(1) pkcs7(7) 2 }
|
|
*
|
|
* SignedData ::= SEQUENCE {
|
|
* version INTEGER,
|
|
* digestAlgorithms DigestAlgorithmIdentifiers,
|
|
* contentInfo ContentInfo,
|
|
* certificates [0] IMPLICIT Certificates OPTIONAL,
|
|
* crls [1] IMPLICIT CertificateRevocationLists OPTIONAL,
|
|
* signerInfos SignerInfos
|
|
* }
|
|
*
|
|
* SignerInfos ::= SET OF SignerInfo
|
|
*
|
|
* SignerInfo ::= SEQUENCE {
|
|
* version Version,
|
|
* issuerAndSerialNumber IssuerAndSerialNumber,
|
|
* digestAlgorithm DigestAlgorithmIdentifier,
|

|
|

|
|

|
|

|

|
* Attributes ::= SET OF Attribute
|
|

|
|
* Attribute ::= SEQUENCE {
|
|
* attrType OBJECT IDENTIFIER,
|
|
* attrValues SET OF AttributeValue
|
|
* }
|
|
*
|
|
* AttributeValue ::= ANY
|
|
*
|
|
* Version ::= INTEGER
|
|
*
|
|
* RecipientInfos ::= SET OF RecipientInfo
|
|
*
|
|
* EncryptedContentInfo ::= SEQUENCE {
|
|
* contentType ContentType,
|
|
* contentEncryptionAlgorithm ContentEncryptionAlgorithmIdentifier,
|
|
* encryptedContent [0] IMPLICIT EncryptedContent OPTIONAL
|
|
* }
|
|
*
|
|
* ContentEncryptionAlgorithmIdentifier ::= AlgorithmIdentifier
|
|
*
|
|
* The AlgorithmIdentifier contains an Object Identifier (OID) and parameters
|
|
* for the algorithm, if any. In the case of AES and DES3, there is only one,
|
|
* the IV.
|
|
*
|
|
* AlgorithmIdentifer ::= SEQUENCE {
|
|
* algorithm OBJECT IDENTIFIER,
|
|
* parameters ANY DEFINED BY algorithm OPTIONAL
|
|
* }
|
|
*
|
|
* EncryptedContent ::= OCTET STRING
|

|
|
* keyEncryptionAlgorithm KeyEncryptionAlgorithmIdentifier,
|
|
* encryptedKey EncryptedKey
|
|
* }
|
|
*
|
|
* IssuerAndSerialNumber ::= SEQUENCE {
|
|
* issuer Name,
|
|
* serialNumber CertificateSerialNumber
|
|
* }
|
|
*
|
|
* CertificateSerialNumber ::= INTEGER
|
|

/* The PKCS#7 structure output by OpenSSL somewhat differs from what
|
|
* other implementations do generate.
|
|
*
|
|
* OpenSSL generates a structure like this:
|
|
* SEQUENCE {
|
|
* ...
|
|
* [0]
|
|
* 26 DA 67 D2 17 9C 45 3C B1 2A A8 59 2F 29 33 38
|
|
* C3 C3 DF 86 71 74 7A 19 9F 40 D0 29 BE 85 90 45
|
|
* ...
|
|
* }
|
|
*
|
|
* Whereas other implementations (and this PKCS#7 module) generate:
|
|
* SEQUENCE {
|
|
* ...
|
|
* [0] {
|
|
* OCTET STRING
|
|
* 26 DA 67 D2 17 9C 45 3C B1 2A A8 59 2F 29 33 38
|
|
* C3 C3 DF 86 71 74 7A 19 9F 40 D0 29 BE 85 90 45
|
|
* ...
|
|
* }
|
|
* }
|
|
*
|
|
* In order to support both, we just capture the context specific
|
|
* field here. The OCTET STRING bit is removed below.
