```

## Remarks

PDFEncryptor encrypts PDF documents with passwords or certificates.

Use PDFEncryptor to encrypt unencrypted and unsigned PDF documents. The PDF specification offers two encryption types:

- Password-based encryption: only someone who knows the password can decrypt the document.
- Certificate-based encryption: only the person who has the private key matching the encryption certificate can decrypt the document.

To encrypt a document with a password, simply assign the password to [OwnerPassword](#ownerpassword-property-secureblackbox_pdfencryptor-class) and [UserPassword](#userpassword-property-secureblackbox_pdfencryptor-class) properties. While PDF allows you to use different passwords for less-restricted owner and more-restricted user, this is rarely used in practice, with the majority of implementations sticking to the same password for both types of users.

To encrypt a document with a certificate, load the recipient's certificate using [CertificateManager](CertificateManager.md#CertificateManager) or [CertificateStorage](CertificateStorage.md#CertificateStorage) components and assign it to the EncryptionCertificate property. The certificate does not need to include the private key.

For both encryption types, use [Permissions](#permissions-property-secureblackbox_pdfencryptor-class) setting to adjust what the viewer can and cannot do. Please note that those are largely declarative, and when a PDF viewing application gets access to the decryption password, it can violate them or simply re-save the document without encryption.

Use [EncryptionAlgorithm](#encryptionalgorithm-property-secureblackbox_pdfencryptor-class) property to tweak the encryption algorithm. [EncryptMetadata](#encryptmetadata-property-secureblackbox_pdfencryptor-class) specifies whether the document information (author name, producer software etc.) should be encrypted together with the rest of the document or kept in the clear.

Finally, provide the input and output locations using [InputFile](#inputfile-property-secureblackbox_pdfencryptor-class) (or [InputBytes](#inputbytes-property-secureblackbox_pdfencryptor-class)) and [OutputFile](#outputfile-property-secureblackbox_pdfencryptor-class) properties and call the [Encrypt](#encrypt-method-secureblackbox_pdfencryptor-class) method to complete the operation. If [OutputFile](#outputfile-property-secureblackbox_pdfencryptor-class) is not assigned, the encrypted document will be generated in [OutputBytes](#outputbytes-property-secureblackbox_pdfencryptor-class).

```text
  encryptor.InputFile = "plain.pdf";
  encryptor.OutputFile = "encrypted.pdf";
  encryptor.OwnerPassword = "password";
  encryptor.UserPassword = "password";
  encryptor.Permissions = pepLowQualityPrint | pepHighQualityPrint;
  encryptor.Encrypt();
```

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. [CertificateManager](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [EncryptionCertificateSubjectKeyID](#encryptioncertificatesubjectkeyid-property-secureblackbox_pdfencryptor-class) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

PDFENCRYPTOR_ENCRYPTIONCERTIFICATECERTTYPE_UNKNOWN(0), PDFENCRYPTOR_ENCRYPTIONCERTIFICATECERTTYPE_X509CERTIFICATE(1), PDFENCRYPTOR_ENCRYPTIONCERTIFICATECERTTYPE_X509CERTIFICATE_REQUEST(2)
```

## Default Value

0

## Remarks

Returns the type of the entity contained in the [Certificate](#Type_Certificate) object.

A [Certificate](#Type_Certificate) object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the [CertificateManager](#CertificateManager) class to load or create new certificate and certificate requests objects.

This property is read-only and not available at design time.

## Data Type

Integer

# EncryptionCertificateCRLDistributionPoints Property ([SecureBlackbox_PDFEncryptor](#pdfencryptor-class) Class)

Contains a list of locations of CRL distribution points used to check this certificate's validity.

## Object Oriented Interface

```text
public function getEncryptionCertificateCRLDistributionPoints();
public function setEncryptionCertificateCRLDistributionPoints($value);
```

## Procedural Interface

```text
secureblackbox_pdfencryptor_get($res, 10 );
secureblackbox_pdfencryptor_set($res, 10, $value );
```

## Default Value

''

## Remarks

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

This property is not available at design time.

## Data Type

String

# EncryptionCertificateCurve Property ([SecureBlackbox_PDFEncryptor](#pdfencryptor-class) Class)

Specifies the elliptic curve associated with the certificate's public key.

## Object Oriented Interface

## Data Type

String

# EncryptionCertificateFingerprint Property ([SecureBlackbox_PDFEncryptor](#pdfencryptor-class) Class)

Contains the fingerprint (a hash imprint) of this certificate.

## Object Oriented Interface

```text
public function getEncryptionCertificateFingerprint();
```

## Procedural Interface

```text
secureblackbox_pdfencryptor_get($res, 12 );
```

## Default Value

''

## Remarks

Contains the fingerprint (a hash imprint) of this certificate.

While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.

This property is read-only and not available at design time.

## Data Type

String

# EncryptionCertificateFriendlyName Property ([SecureBlackbox_PDFEncryptor](#pdfencryptor-class) Class)

Contains an associated alias (friendly name) of the certificate.

## Object Oriented Interface

```text
public function getEncryptionCertificateFriendlyName();
```

## Procedural Interface

```text
secureblackbox_pdfencryptor_get($res, 13 );
```

## Default Value

''

## Remarks

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

This property is read-only and not available at design time.

## Data Type

String

# EncryptionCertificateHandle Property ([SecureBlackbox_PDFEncryptor](#pdfencryptor-class) Class)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

## Object Oriented Interface

```text
public function getEncryptionCertificateHandle();
public function setEncryptionCertificateHandle($value);
```

## Procedural Interface

```text
secureblackbox_pdfencryptor_get($res, 14 );
secureblackbox_pdfencryptor_set($res, 14, $value );
```

## Default Value

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

```text
  pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
```

This property is not available at design time.

## Data Type

Long64

# EncryptionCertificateHashAlgorithm Property ([SecureBlackbox_PDFEncryptor](#pdfencryptor-class) Class)

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing).

## Object Oriented Interface

```text
public function getEncryptionCertificateHashAlgorithm();
public function setEncryptionCertificateHashAlgorithm($value);
```

## Procedural Interface

```text
secureblackbox_pdfencryptor_get($res, 15 );
secureblackbox_pdfencryptor_set($res, 15, $value );
```

## Default Value

''

## Remarks

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use [EncryptionCertificateSigAlgorithm](#encryptioncertificatesigalgorithm-property-secureblackbox_pdfencryptor-class) to find out the hash algorithm that is part of the certificate signature.

If *StaticDNS* of the class is set to "*local*", the property returns/restores the rules from/to the internal storage of the class. If *StaticDNS* of the class is set to "*global*", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

**Tag**: Allows to store any custom data.Use this config property to store any custom data.

**TLSSessionGroup**: Specifies the group name of TLS sessions to be used for session resumption.Use this property to limit the search of cached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the classes.

**TLSSessionLifetime**: Specifies lifetime in seconds of the cached TLS session.Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

**UseOCSPResponseObjectCaching**: Specifies whether reuse of loaded OCSP response objects is enabled.This setting enables or disables the caching of OCSP response objects. When set to true (the default value), the system checks if a OCSP response object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where OCSP response objects are frequently used.

**UseOwnDNSResolver**: Specifies whether the client components should use own DNS resolver.Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

**UseSharedSystemStorages**: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.Set this global property to false to make each validation run use its own copy of system certificate stores.

**UseSystemNativeSizeCalculation**: An internal CryptoAPI access tweak.This is an internal setting. Please do not use it unless instructed by the support team.

If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

**UseSystemRandom**: Enables or disables the use of the OS PRNG.Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

**XMLRDNDescriptorName[OID]**: Defines an OID mapping to descriptor names for the certificate's IssuerRDN or SubjectRDN.This property defines custom mappings between Object Identifiers (OIDs) and descriptor names. This mapping specifies how the certificate's issuer and subject information (ds:IssuerRDN and ds:SubjectRDN elements respectively) are represented in XML signatures.

The property accepts comma-separated values where the first descriptor name is used when the OID is mapped, and subsequent values act as aliases for parsing.

Syntax:
