ICertProvider.OpenSignerBase64

Fore Syntax

OpenSignerBase64(Name: String; Data: String): ICertSigner;

Fore.NET Syntax

OpenSignerBase64(Name: String; Data: String): Prognoz.Platform.Interop.Metabase.ICertSigner;

Parameters

Name. Signer name.

Data. Contents of the certificate private key in the Base64 format.

Description

The OpenSignerBase64 method returns signer for certificate for which private key is sent.

Fore Example

Function SampleSigner(Code: String; PrivateKey: String): String;
Var
    Package: ISecurityPackage;
    Provider: ICertProvider;
    Signer: ICertSigner;
    Signature: String;
Begin
    Package := New StandardSecurityPackage.Create;
    Provider := Package.CertProvider;
    //Comparison of random value and block of data
    Provider.Code(Math.RandBetweenI(Integer.MinValue, Integer.MaxValue).ToString) := Code;
    //Get signer
    Signer := Provider.OpenSignerBase64("sp", PrivateKey);
    //Sign with digital signature
    Signature := Signer.Sign(Code);
    Return Signature;
End Function SampleSigner;

The specified function is used to sign block of data with digital signature. Block of data and private key are sent as initial parameters. On the output function returns block of data signed with digital signature.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

    Provider: ICertProvider;
    Signer: ICertSigner;
    Signature: String;
Begin
    Provider := Package.CertProvider;
    //Comparison of random value and block of data
    Provider.Code[CMath.RandBetweenI(Integer.MinValue, Integer.MaxValue).ToString()] := Code;
    //Get signer
    Signer := Provider.OpenSignerBase64("sp", PrivateKey);
    //Sign with digital signature
    Signature := Signer.Sign(Code);
    Return Signature;
End Function;
