Implements RSA public-key cryptography to encrypt/decrypt and sign/verify messages.

Syntax

TipcRSA

Remarks

The RSA component implements RSA public-key cryptography to encrypt/decrypt messages and sign/verify hash signatures.

To begin you must either specify an existing key or create a new key. Existing private keys may be specified by setting the Key* properties. To create a new key call CreateKey. Alternatively an existing certificate may be specified by setting the Certificate* properties

Signing

To sign data first set Key or Certificate. Specify the input data using InputFile or InputMessage. Next call Sign. The component will populate HashValue and HashSignature. After calling Sign the public key must be sent to the recipient along with HashSignature.

Encrypting

To encrypt data set RecipientKey or RecipientCert. Specify the input data using InputFile or InputMessage. Next call Encrypt. The component will populate OutputMessage, or write to the file specified by OutputFile.

Signature Verification

To verify a signature specify the input data using InputFile or InputMessage. Set SignerKey or SignerCert. Next set HashSignature and call VerifySignature. The VerifySignature method will return True if the signature was successfully verified.

Decrypting

To decrypt data first set Key or Certificate. Specify the input data using InputFile or InputMessage. Next call Decrypt. The component will populate OutputMessage, or write to the file specified by OutputFile.

Input and Output Properties

The component will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

When using streams you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

RSA Keys

A RSA key is made up of a number of individual parameters.

The public key consists of the following parameters:

The component also includes the PublicKey property which holds the PEM formatted public key for ease of use. This is helpful if you are in control of both sides of the encryption/signing and decryption/signature verification process. When sending the public key to a recipient note that not all implementations will support using the PEM formatted value in PublicKey in which case the individual parameters must be sent.

The private key may be represented in one of two ways. Both are mathematically equivalent. Private key format 1:

Private key format 2 is simpler but has decreased performance when decrypting and signing. This format is: The component also include the PrivateKey property which holds the PEM formatted private key for ease of use. This is helpful for storing the private key more easily.

Config Settings (RSA Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

RSA Config Settings

CloseInputStreamAfterProcessing:   Determines whether or not the input stream is closed after processing.

Determines whether or not the input stream set by SetInputStream is closed after processing is complete. The default value is True.

CloseOutputStreamAfterProcessing:   Determines whether or not the output stream is closed after processing.

Determines whether or not the output stream set by SetOutputStream is closed after processing is complete. The default value is True.

KeyFormat:   How the public and private key are formatted.

This setting controls the format of PublicKey and PrivateKey. By default these properties hold PEM formatted public and private key data. When set to 1 (XML) the keys are stored in a XML format. This only affects the values returned by the component; the actual keys remain the same regardless of this setting. Possible values are:

  • 0 (PEM - PKCS#1)
  • 1 (XML)
  • 2 (PEM - PKCS#8 - default)
The default value is 2 (PEM - PKCS#8).
KeySize:   The size, in bits, of the secret key.

This specifies the size, in bits, of the secret key. The minimum key size for RSA is 384. The maximum key size is 4096. Note that large values such as 4096 will impact performance. The default value is 1024.

OAEPMGF1HashAlgorithm:   The MGF1 hash algorithm used with OAEP.

This configuration setting specifies the MGF1 hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

  • "SHA384"
  • "SHA512"
  • "RIPEMD160"
  • "MD2"
  • "MD5"
  • "MD5SHA1"

Note: This setting is not applicable when UseFIPSCompliantAPI is set to True or when the private key of the signing certificate is not exportable since the underlying system implementation does not support separate OAEPRSAHashAlgorithm and OAEPMGF1HashAlgorithm values. In this case the OAEPRSAHashAlgorithm is also used for MGF1.

OAEPParams:   The hex encoded OAEP parameters.

This configuration setting optionally specifies Optimal Asymmetric Encryption Padding (OAEP) parameters to be used when UseOAEP is set to True. The specified value should be hex encoded.

OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

  • "SHA1"
  • "SHA224"
  • "SHA256" (default)
  • "SHA384"
  • "SHA512"
  • "RIPEMD160"

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to True to mask sensitive data. The default is True.

This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI:   Tells the component whether or not to use the system security libraries or an internal implementation.

When set to False, the component will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to True tells the component to use the internal implementation instead of using the system security libraries.

This setting is set to False by default on all platforms.
