SignerInfo(Certificate, SubjectIdentifierType)

Creates a new instance of SignerInfo that defines a signer corresponding to the specified certificate. An associated private key for the certificate must be available. Use SignerInfo(Certificate, SignatureParameters, SubjectIdentifierType) to specify RSASSA-PSS parameters.
SignerInfo(Certificate, SubjectIdentifierType, SignatureHashAlgorithm)

Creates a new instance of SignerInfo that defines a signer corresponding to the specified certificate. An associated private key for the certificate must be available. Use SignerInfo(Certificate, SignatureParameters, SubjectIdentifierType) to specify RSASSA-PSS parameters.
SignerInfo(Certificate, SignatureParameters)

Creates a new instance of SignerInfo that defines a signer corresponding to the specified certificate. An associated private key for the certificate must be available.
SignerInfo(Certificate, SignatureParameters, SubjectIdentifierType)
