Field Documentation

EncryptWithPublicKey

CMUTIL_String *(* CMUTIL_RSACrypto::EncryptWithPublicKey) (CMUTIL_RSACrypto *crypto, CMUTIL_String *plain, CMUTIL_PublicKey *pubKey)

Encrypts plain text using an RSA public key.

Parameters

crypto	The RSA crypto object.
plain	The plain text to encrypt.
pubKey	The public key to use for encryption.

Returns

The encrypted data as a CMUTIL_String object, or NULL on failure.

EncryptWithPrivateKey

CMUTIL_String *(* CMUTIL_RSACrypto::EncryptWithPrivateKey) (CMUTIL_RSACrypto *crypto, CMUTIL_String *plain, CMUTIL_PrivateKey *privKey)

Encrypts plain text using an RSA private key.

Parameters

crypto	The RSA crypto object.
plain	The plain text to encrypt.
privKey	The private key to use for encryption.

Returns

The encrypted data as a CMUTIL_String object, or NULL on failure.

DecryptWithPublicKey

CMUTIL_String *(* CMUTIL_RSACrypto::DecryptWithPublicKey) (CMUTIL_RSACrypto *crypto, CMUTIL_String *encrypted, CMUTIL_PublicKey *pubKey)

Decrypts data using an RSA public key.

Parameters

crypto	The RSA crypto object.
encrypted	The encrypted data to decrypt.
pubKey	The public key to use for decryption.

Returns

The decrypted data as a CMUTIL_String object, or NULL on failure.

DecryptWithPrivateKey

CMUTIL_String *(* CMUTIL_RSACrypto::DecryptWithPrivateKey) (CMUTIL_RSACrypto *crypto, CMUTIL_String *encrypted, CMUTIL_PrivateKey *privKey)

Decrypts data using an RSA private key.

Parameters

crypto	The RSA crypto object.
encrypted	The encrypted data to decrypt.
privKey	The private key to use for decryption.

Returns

The decrypted data as a CMUTIL_String object, or NULL on failure.

Sign

CMUTIL_String *(* CMUTIL_RSACrypto::Sign) (CMUTIL_RSACrypto *crypto, CMUTIL_String *plain, CMUTIL_PrivateKey *privKey)

Digitally signs plain text using an RSA private key.

Parameters

crypto	The RSA crypto object.
plain	The data to sign.
privKey	The private key to use for signing.

Returns

The digital signature as a CMUTIL_String object, or NULL on failure.

VerifySignature

CMBool(* CMUTIL_RSACrypto::VerifySignature) (CMUTIL_RSACrypto *crypto, CMUTIL_String *plain, CMUTIL_String *signature, CMUTIL_PublicKey *pubKey)

Verifies a digital signature using an RSA public key.

Parameters

crypto	The RSA crypto object.
plain	The original data that was signed.
signature	The signature to verify.
pubKey	The public key to use for verification.

Returns

CMTrue if the signature is valid, CMFalse otherwise.

Destroy

void(* CMUTIL_RSACrypto::Destroy) (CMUTIL_RSACrypto *crypto)

Destroys the RSA crypto object.

Parameters

crypto

The RSA crypto object to destroy.
