*
* 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,
* authenticatedAttributes [0] IMPLICIT Attributes OPTIONAL,
* digestEncryptionAlgorithm DigestEncryptionAlgorithmIdentifier,
* encryptedDigest EncryptedDigest,
* unauthenticatedAttributes [1] IMPLICIT Attributes OPTIONAL
* }
*
* EncryptedDigest ::= OCTET STRING
*
* 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
*
* RecipientInfo ::= SEQUENCE {
* version Version,
* issuerAndSerialNumber IssuerAndSerialNumber,
* keyEncryptionAlgorithm KeyEncryptionAlgorithmIdentifier,
* encryptedKey EncryptedKey
* }
*
* IssuerAndSerialNumber ::= SEQUENCE {
* issuer Name,
* serialNumber CertificateSerialNumber
* }
*
* CertificateSerialNumber ::= INTEGER
*
* KeyEncryptionAlgorithmIdentifier ::= AlgorithmIdentifier
*
* EncryptedKey ::= OCTET STRING

/* The PKCS#7 structure output by OpenSSL somewhat differs from what

* OpenSSL generates a structure like this:

* [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.
