Methods
| Method | Description |
|---|---|
| getDigestAlgorithms() | Gets the array of message-digest algorithm identifiers. |
| getEncapsulatedContent() | Gets the signed content, consisting of a content type identifier and the content itself. |
| getCertificates() | Gets the collection of certificates. |
| getSigners() | Gets the collection of per-signer information packages. |
| getSignTime() | Gets the time at which the signer (purportedly) performed the signing process. |
getDigestAlgorithms()
public final Oid[] getDigestAlgorithms()
Gets the array of message-digest algorithm identifiers. There may be any number of elements in the collection, including zero.
Returns: com.groupdocs.metadata.core.Oid[] - The array of message-digest algorithm identifiers.
getEncapsulatedContent()
public final CmsEncapsulatedContent getEncapsulatedContent()
Gets the signed content, consisting of a content type identifier and the content itself.
Returns: CmsEncapsulatedContent - The signed content, consisting of a content type identifier and the content itself.
getCertificates()
public final CmsCertificate[] getCertificates()
Gets the collection of certificates.
Returns: com.groupdocs.metadata.core.CmsCertificate[] - The collection of certificates.
It is intended that the set of certificates be sufficient to contain certification paths from a recognized “root” or “top-level certification authority” to all of the signers in the SignerInfo field.
getSigners()
public final CmsSigner[] getSigners()
Gets the collection of per-signer information packages.
Returns: com.groupdocs.metadata.core.CmsSigner[] - The collection of per-signer information packages.
There may be any number of elements in the collection, including zero.
getSignTime()
public Date getSignTime()
Gets the time at which the signer (purportedly) performed the signing process.
Returns: java.util.Date - The time at which the signer (purportedly) performed the signing process.
