inlinestatic

Verifies a single certificate for the current date.

Parameters

cert	the certificate to verify
crls	the certificate revocation list or null

Returns

a String with the error description or null if no error

VerifyCertificate() [2/2]

static String iText.Signatures.CertificateVerification.VerifyCertificate ( IX509Certificate  cert, ICollection< IX509Crl >  crls, DateTime  calendar  )

inlinestatic

Verifies a single certificate.

Parameters

cert	the certificate to verify
crls	the certificate revocation list or null
calendar	the date, shall not be null

Returns

a String with the error description or null if no error

VerifyCertificates() [1/4]

static IList<VerificationException> iText.Signatures.CertificateVerification.VerifyCertificates ( IX509Certificate[]  certs, List< IX509Certificate >  keystore  )

inlinestatic

Verifies a certificate chain against a KeyStore for the current date.

Parameters

certs	the certificate chain
keystore	the KeyStore

Returns

null if the certificate chain could be validated or a Object[]{cert,error} where cert is the failed certificate and error is the error message

inlinestatic

Verifies a certificate chain against a KeyStore for the current date.

Parameters

certs	the certificate chain
keystore	the KeyStore
crls	the certificate revocation list or null

Returns

empty list if the certificate chain could be validated or a Object[]{cert,error} where cert is the failed certificate and error is the error message
