cert_bytes Property

Returns the raw certificate data in DER format.

Syntax

def get_cert_bytes() -> bytes: ...

cert_bytes = property(get_cert_bytes, None)

Remarks

Returns the raw certificate data in DER format.

This property is read-only.

cert_ca Property

Indicates whether the certificate has a CA capability.

Syntax

def get_cert_ca() -> bool: ...
def set_cert_ca(value: bool) -> None: ...

cert_ca = property(get_cert_ca, set_cert_ca)

Default Value

FALSE

Remarks

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

cert_ca_key_id Property

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

Syntax

def get_cert_ca_key_id() -> bytes: ...

cert_ca_key_id = property(get_cert_ca_key_id, None)

Remarks

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

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 generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the cert_subject_key_id setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

This property is read-only.

cert_cert_type Property

Returns the type of the entity contained in the Certificate object.

Syntax

def get_cert_cert_type() -> int: ...

cert_cert_type = property(get_cert_cert_type, None)

Default Value

0

Remarks

Returns the type of the entity contained in the Certificate object.

A 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 class to load or create new certificate and certificate requests objects.

This property is read-only.

cert_crl_distribution_points Property

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

Syntax

def get_cert_crl_distribution_points() -> str: ...
def set_cert_crl_distribution_points(value: str) -> None: ...

cert_crl_distribution_points = property(get_cert_crl_distribution_points, set_cert_crl_distribution_points)

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.

cert_curve Property

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

Syntax

def get_cert_curve() -> str: ...
def set_cert_curve(value: str) -> None: ...

cert_curve = property(get_cert_curve, set_cert_curve)

Default Value

""

Remarks

Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

Syntax

def get_cert_fingerprint() -> str: ...

cert_fingerprint = property(get_cert_fingerprint, None)

Default Value

""

Remarks

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.

cert_friendly_name Property

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

Syntax

def get_cert_friendly_name() -> str: ...

cert_friendly_name = property(get_cert_friendly_name, None)

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.

cert_handle Property

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

Syntax

def get_cert_handle() -> int: ...
def set_cert_handle(value: int) -> None: ...

cert_handle = property(get_cert_handle, set_cert_handle)

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

cert_hash_algorithm Property

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

Syntax

def get_cert_hash_algorithm() -> str: ...
def set_cert_hash_algorithm(value: str) -> None: ...

cert_hash_algorithm = property(get_cert_hash_algorithm, set_cert_hash_algorithm)

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 cert_sig_algorithm to find out the hash algorithm that is part of the certificate signature.

cert_issuer Property

The common name of the certificate issuer (CA), typically a company name.

Syntax

def get_cert_issuer() -> str: ...

cert_issuer = property(get_cert_issuer, None)

Syntax

def get_cert_key_bits() -> int: ...

cert_key_bits = property(get_cert_key_bits, None)

Default Value

0

Remarks

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the cert_public_key_bytes or cert_private_key_bytes property would typically contain auxiliary values, and therefore be longer.

This property is read-only.

cert_key_fingerprint Property

Returns a SHA1 fingerprint of the public key contained in the certificate.

Syntax

def get_cert_key_fingerprint() -> str: ...

cert_key_fingerprint = property(get_cert_key_fingerprint, None)

Default Value

""

Remarks

Returns a SHA1 fingerprint of the public key contained in the certificate.

Note that the key fingerprint is different from the certificate fingerprint accessible via the cert_fingerprint property. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

This property is read-only.

cert_key_usage Property

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

Syntax

def get_cert_key_usage() -> int: ...
def set_cert_key_usage(value: int) -> None: ...

cert_key_usage = property(get_cert_key_usage, set_cert_key_usage)

Default Value

cert_ocsp_locations = property(get_cert_ocsp_locations, set_cert_ocsp_locations)

Default Value

""

Remarks

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Set this property before calling the certificate manager's generate method to propagate it to the new certificate.

The OCSP locations 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.

cert_ocsp_no_check Property

Accessor to the value of the certificate's ocsp-no-check extension.

Syntax

def get_cert_ocsp_no_check() -> bool: ...
def set_cert_ocsp_no_check(value: bool) -> None: ...

This property is read-only.

cert_policy_i_ds Property

Contains identifiers (OIDs) of the applicable certificate policies.

Syntax

def get_cert_policy_i_ds() -> str: ...
def set_cert_policy_i_ds(value: str) -> None: ...

cert_policy_i_ds = property(get_cert_policy_i_ds, set_cert_policy_i_ds)

Default Value

""

Remarks

Contains identifiers (OIDs) of the applicable certificate policies.

The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.

Set this property when generating a certificate to propagate the policies information to the new certificate.

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

cert_private_key_bytes Property

Returns the certificate's private key in DER-encoded format.

Syntax

def get_cert_private_key_bytes() -> bytes: ...

cert_private_key_bytes = property(get_cert_private_key_bytes, None)

Remarks

Returns the certificate's private key in DER-encoded format. It is normal for this property to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.

This property is read-only.

cert_private_key_exists Property

Indicates whether the certificate has a usable private key associated with it.

Syntax

def get_cert_private_key_exists() -> bool: ...

cert_private_key_exists = property(get_cert_private_key_exists, None)

Default Value

FALSE

Remarks

Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.

This property is independent from cert_private_key_bytes, and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.

This property is read-only.

cert_private_key_extractable Property

Indicates whether the private key is extractable (exportable).

Syntax

def get_cert_private_key_extractable() -> bool: ...

cert_private_key_extractable = property(get_cert_private_key_extractable, None)

Remarks

Indicates whether the certificate is self-signed (root) or signed by an external CA.

This property is read-only.

cert_serial_number Property

Returns the certificate's serial number.

Syntax

def get_cert_serial_number() -> bytes: ...
def set_cert_serial_number(value: bytes) -> None: ...

cert_serial_number = property(get_cert_serial_number, set_cert_serial_number)

Remarks

Returns the certificate's serial number.

The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.

cert_sig_algorithm Property

Indicates the algorithm that was used by the CA to sign this certificate.

Syntax

def get_cert_sig_algorithm() -> str: ...

cert_sig_algorithm = property(get_cert_sig_algorithm, None)

Default Value

""

Remarks

Indicates the algorithm that was used by the CA to sign this certificate.

A signature algorithm typically combines hash and public key algorithms together, such as sha256WithRSAEncryption or ecdsa-with-SHA256.

This property is read-only.

cert_source Property

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

Syntax

cert_subject_alternative_name = property(get_cert_subject_alternative_name, set_cert_subject_alternative_name)

Default Value

""

Remarks

Returns or sets the value of the Subject Alternative Name extension of the certificate.

Subject alternative names are used to provide additional names that are impractical to store in the main cert_subject_rdn field. For example, it is often used to store all the domain names that a TLS certificate is authorized to protect.

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

cert_subject_key_id Property

crypto_key_handle = property(get_crypto_key_handle, set_crypto_key_handle)

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

crypto_key_id Property

Provides access to a storage-specific key identifier.

Syntax

def get_crypto_key_id() -> bytes: ...
def set_crypto_key_id(value: bytes) -> None: ...

crypto_key_id = property(get_crypto_key_id, set_crypto_key_id)

Remarks

Provides access to a storage-specific key identifier. Key identifiers are used by cryptographic providers to refer to a particular key and/or distinguish between different keys. They are typically unique within a storage, but there is no guarantee that a particular cryptoprovider will conform to that (or will assign any key IDs at all).

crypto_key_iv Property

The initialization vector (IV) of a symmetric key.

Syntax

def get_crypto_key_valid() -> bool: ...

crypto_key_valid = property(get_crypto_key_valid, None)

Default Value

FALSE

Remarks

Returns True if this key is valid. The term Valid highly depends on the kind of the key being stored. A symmetric key is considered valid if its length fits the algorithm being set. The validity of an RSA key also ensures that the RSA key elements (primes, exponents, and modulus) are consistent.

This property is read-only.

fips_mode Property

Reserved.

Syntax

def get_fips_mode() -> bool: ...
def set_fips_mode(value: bool) -> None: ...
