Remarks

CryptoKeyManager allows you to load, save, generate, import, and export low-level cryptographic keys. Two examples of such keys are raw RSA keys stored in PKCS1 format or AES256 keys. CryptoKeyManager supports asymmetric, symmetric, and HMAC keys.

CryptoKeyManager is a typical companion for low-level cryptography classes, such as PublicKeyCrypto, SymmetricCrypto, and HashFunction. It can also be used to provide external key material to certificate objects, and to derive cryptographic keys from passwords.

Use ImportBytes or ImportFromFile method to load the key material from a buffer or file. Use ImportFromCert (and remember to assign the certificate object to the Certificate property before calling it) to import a key from an X.509 certificate. Once loaded, the key will be available in the Key property. // Loading an AES key and setting its IV CryptoKeyManager.ImportBytes(Key, kffDER, "AES256", "", "", ktSecret, ""); CryptoKeyManager.Key.IV = IV; // Loading an ECDSA private key from a file CryptoKeyManager.ImportFromFile("ec-secp256k1-priv-key.pem", kffAuto, "ECDSA", "NISTP256", "", ktSecret, ""); // Loading an ECDSA public key from a file CryptoKeyManager.ImportFromFile("ec-secp256k1-pub-key.pem", kffAuto, "ECDSA", "NISTP256", "", ktPublic, ""); // Importing a private key from a certificate object CertMgr.ImportFromFile("cert.pfx", "password"); CryptoKeyManager.Certificate = CertMgr.Certificate; CryptoKeyManager.ImportFromCert();

To generate a new key or keypair use Generate method. You can export the generated key using ExportBytes or ExportToFile method. You can attach the generated or loaded key to an external certificate object using the ExportToCert method. // Generating an EdDSA Curve25519 keypair CryptoKeyManager.Generate("EDDSA", "CURVE25519", "", 256); // Generating an ECDSA NIST P256 curve keypair CryptoKeyManager.Generate("ECDSA", "NISTP256", "", 256); // Generating an RSA 2048 bit keypair CryptoKeyManager.Generate("RSA", "", "", 2048); // Generating a symmetric AES256 key CryptoKeyManager.Generate("AES256", "", "", 256);

Use DeriveKey to derive a strong cryptographic key from a password using one of supported key derivation functions (KDFs): CryptoKeyManager.DerivationAlgorithm = "PKCS5"; CryptoKeyManager.HMACAlgorithm = "SHA256"; CryptoKeyManager.DeriveIterations = 10000; CryptoKeyManager.DeriveKey(256, "password", "hex:41424344"); Key = CryptoKeyManager.Key.Key;

CryptoKeyManager supports the majority of modern cryptographic algorithms:

• Asymmetric: RSA, ECDSA, EdDSA, ElGamal, DSS, Diffie-Hellman
• Symmetric: AES, Blowfish, Camellia, CAST5, ChaCha20, DES, 3DES-EDE, IDEA, RC2, RC4, Serpent, Twofish.
• KDFs: PKCS5, PBKDF2 (an alias to PKCS5), BCrypt, SCrypt, Argon2d, Argon2i, Argon2id.

See the "Supported Algorithms" section in the FAQ for the complete list.

Note: CryptoKeyManager can only work with one cryptographic key at a time. Use CryptoKeyStorage to access media containing more than one key.

CertBytes Property (SecureBlackbox_CryptoKeyManager Class)

Returns the raw certificate data in DER format.

Object Oriented Interface

public function getCertBytes();

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 1 );

Remarks

Returns the raw certificate data in DER format.

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

Data Type

Byte Array

CertCA Property (SecureBlackbox_CryptoKeyManager Class)

Indicates whether the certificate has a CA capability.

Object Oriented Interface

public function getCertCA();
public function setCertCA($value);

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 2 );
secureblackbox_cryptokeymanager_set($res, 2, $value );

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.

This property is not available at design time.

Data Type

Boolean

CertCAKeyID Property (SecureBlackbox_CryptoKeyManager Class)

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

Object Oriented Interface

public function getCertCAKeyID();

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 3 );

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 CertSubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

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

Data Type

Byte Array

CertCertType Property (SecureBlackbox_CryptoKeyManager Class)

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

Object Oriented Interface

public function getCertCertType();

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 4 );

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 and not available at design time.

Data Type

Integer

CertCRLDistributionPoints Property (SecureBlackbox_CryptoKeyManager Class)

secureblackbox_cryptokeymanager_set($res, 5, $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

CertCurve Property (SecureBlackbox_CryptoKeyManager Class)

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

Object Oriented Interface

public function getCertCurve();
public function setCertCurve($value);

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 6 );
secureblackbox_cryptokeymanager_set($res, 6, $value );

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

CertFriendlyName Property (SecureBlackbox_CryptoKeyManager Class)

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

Object Oriented Interface

public function getCertFriendlyName();

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 8 );

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

CertHandle Property (SecureBlackbox_CryptoKeyManager Class)

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

Object Oriented Interface

secureblackbox_cryptokeymanager_set($res, 9, $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. pdfSigner.setSigningCertHandle(certMgr.getCertHandle());

This property is not available at design time.

Data Type

Long64

CertHashAlgorithm Property (SecureBlackbox_CryptoKeyManager Class)
