9 *
10 * The ASN.1 representation of PKCS#7 is as follows
11 * (see RFC #2315 for details, http://www.ietf.org/rfc/rfc2315.txt):
12 *
13 * A PKCS#7 message consists of a ContentInfo on root level, which may
14 * contain any number of further ContentInfo nested into it.
15 *
16 * ContentInfo ::= SEQUENCE {
17 * contentType ContentType,
18 * content [0] EXPLICIT ANY DEFINED BY contentType OPTIONAL
19 * }
20 *
21 * ContentType ::= OBJECT IDENTIFIER
22 *
23 * EnvelopedData ::= SEQUENCE {
24 * version Version,
25 * recipientInfos RecipientInfos,
26 * encryptedContentInfo EncryptedContentInfo
27 * }
28 *
29 * EncryptedData ::= SEQUENCE {
30 * version Version,
31 * encryptedContentInfo EncryptedContentInfo
32 * }
33 *
34 * id-signedData OBJECT IDENTIFIER ::= { iso(1) member-body(2)
35 * us(840) rsadsi(113549) pkcs(1) pkcs7(7) 2 }
36 *
37 * SignedData ::= SEQUENCE {
38 * version INTEGER,
39 * digestAlgorithms DigestAlgorithmIdentifiers,
40 * contentInfo ContentInfo,
41 * certificates [0] IMPLICIT Certificates OPTIONAL,
42 * crls [1] IMPLICIT CertificateRevocationLists OPTIONAL,
43 * signerInfos SignerInfos
44 * }
45 *
46 * SignerInfos ::= SET OF SignerInfo
47 *
48 * SignerInfo ::= SEQUENCE {
49 * version Version,
50 * issuerAndSerialNumber IssuerAndSerialNumber,
51 * digestAlgorithm DigestAlgorithmIdentifier,
52 * authenticatedAttributes [0] IMPLICIT Attributes OPTIONAL,
53 * digestEncryptionAlgorithm DigestEncryptionAlgorithmIdentifier,
54 * encryptedDigest EncryptedDigest,
55 * unauthenticatedAttributes [1] IMPLICIT Attributes OPTIONAL
56 * }
57 *
58 * EncryptedDigest ::= OCTET STRING
59 *
60 * Attributes ::= SET OF Attribute
61 *
62 * Attribute ::= SEQUENCE {
63 * attrType OBJECT IDENTIFIER,
64 * attrValues SET OF AttributeValue
65 * }
66 *
67 * AttributeValue ::= ANY
68 *
69 * Version ::= INTEGER
70 *
71 * RecipientInfos ::= SET OF RecipientInfo
72 *
73 * EncryptedContentInfo ::= SEQUENCE {
74 * contentType ContentType,
75 * contentEncryptionAlgorithm ContentEncryptionAlgorithmIdentifier,
76 * encryptedContent [0] IMPLICIT EncryptedContent OPTIONAL
77 * }
78 *
79 * ContentEncryptionAlgorithmIdentifier ::= AlgorithmIdentifier
80 *
81 * The AlgorithmIdentifier contains an Object Identifier (OID) and parameters
82 * for the algorithm, if any. In the case of AES and DES3, there is only one,
83 * the IV.
84 *
85 * AlgorithmIdentifer ::= SEQUENCE {
86 * algorithm OBJECT IDENTIFIER,
87 * parameters ANY DEFINED BY algorithm OPTIONAL
88 * }
89 *
90 * EncryptedContent ::= OCTET STRING
91 *
92 * RecipientInfo ::= SEQUENCE {
93 * version Version,
94 * issuerAndSerialNumber IssuerAndSerialNumber,
95 * keyEncryptionAlgorithm KeyEncryptionAlgorithmIdentifier,
96 * encryptedKey EncryptedKey
97 * }
98 *
99 * IssuerAndSerialNumber ::= SEQUENCE {
100 * issuer Name,
101 * serialNumber CertificateSerialNumber
102 * }
103 *
104 * CertificateSerialNumber ::= INTEGER
105 *
106 * KeyEncryptionAlgorithmIdentifier ::= AlgorithmIdentifier
107 *
108 * EncryptedKey ::= OCTET STRING
