Remarks
The S/MIME class implements the S/MIME V3 standard for encryption and decryption using Public Key Cryptography Standards (PKCS). In addition, the class can be used to both generate and verify RSA digital signatures. Using this class for decrypting or signing requires a valid digital certificate with a private key.
Before performing an operation the input and output values should be specified.
Input and Output Properties
The class 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:
- OutputFile
- OutputMessage: The output data is written to this property if no other destination is specified.
The headers of the input message (if any) will be read from InputMessageHeaders or InputMessageHeadersString.
The headers of the resulting message will be available in the OutputMessageHeaders and OutputMessageHeadersString properties.
Signing
To sign the current data included in the input message with a certificate, the Certificate property must be set to a valid Certificate object for the signing certificate. The IncludeCertificate and DetachedSignature properties allow you to specify additional details about the signing process. By setting IncludeCertificate to True, digital certificates can be encoded and included in message signature when signing the document. Including a certificate is the preferred method of building signed messages. In addition the S/MIME class can also generate PKCS #7 formatted detached digital signatures and envelopes by specifying DetachedSignature.
Encrypting
To encrypt a message with the class in a PKCS envelope, you must first specify the Certificate for each recipient in the RecipientCerts properties to encrypt the message with. You can easily add these with the AddRecipientCert method. Once you have done this you can call the Encrypt method to encrypt the message with the recipient certificates.
In addition, the class allows you to sign and encrypt simultaneously with the SignAndEncrypt method. You must set all of the properties needed for both Sign and Encrypt
The result of the encrypted or signed data will be replaced in the OutputMessage property and the OutputMessageHeaders property will be filled with the appropriate mime headers if applicable.
Decrypting
Decrypting PKCS envelopes is handled with the Decrypt method. When this method is called, the class will attempt to find an appropriate certificate in the Certificate property that matches the encrypting certificate. If it cannot find an appropriate certificate, an exception will be thrown and the message will not be decrypted.
Verifying Signatures
In addition, the S/MIME class can be used to verify signatures included in signed messages or documents. After specifying the input, VerifySignature can then be used to verify the signature. If the message does not have a certificate attached, more then likely an exception will be thrown and the class will not be able to verify the signature. If VerifySignature is successful, the SignerCert and SignerCertChain properties will be filled with the certificate information of the message signer. This information can be used to verify the signing certificates.
Similar to SignAndEncrypt, DecryptAndVerifySignature can be used to both decrypt and verify the message in Message.

The value in DetachedSignature is ignored: the class will always generate an attached signature when calling this method. All other properties used by calling the Sign and Encrypt methods are used in the same manner.
Note: The message headers, including the Sender, Recipient(s), and Subject, are not encrypted. If this is sensitive information, consider including these headers in the message body as a MIME entity and providing other headers for the S/MIME wrapper.

Parameter List
'issuer'
'serialnumber'
'subjectkeyidentifier'
'encryptionalgorithm'
Remarks
When GetRecipientInfo is called on a valid encrypted message, this event will fire once for each recipient certificate that the message has been encrypted for. This may be used to identify the certificate to load.
Issuer is the subject of the issuer certificate.
SerialNumber is the serial number of the encryption certificate.
SubjectKeyIdentifier is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string.
EncryptionAlgorithm is the encryption algorithm used to encrypt the message. Possible values are as follows:
- "3DES"

SignerCertInfo Event (IPWorksSMIME_SMIME Class)
This event is fired during verification of the signed message.
Object Oriented Interface
public function fireSignerCertInfo($param);
Procedural Interface
ipworkssmime_smime_register_callback($res, 3, array($this, 'fireSignerCertInfo'));
Parameter List
'issuer'
'serialnumber'
'subjectkeyidentifier'
'certencoded'
Remarks
During verification, this event will be raised while parsing the signer's certificate information. The parameters that are populated depend on the options used when the message was originally signed. This information may be used to select the correct certificate for SignerCert to verify the signature. The following parameters may be populated:
Issuer specifies the subject of the issuer of the certificate used to sign the message.
SerialNumber is the serial number of the certificate used to sign the message.
SubjectKeyIdentifier is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string.
CertEncoded is the PEM (Base64 encoded) public certificate needed to verify the signature.
Note: When this value is present, the class will automatically use this value to perform signature verification.
The SignerCert property may be set from within this event. In this manner, the decision of which signer certificate to load may be delayed until the parameters of this event are inspected and the correct certificate can be located and loaded.

UseInternalSecurityAPI:
Tells the class whether or not to use the system security libraries or an internal implementation.
When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.
Setting this setting to true tells the class to use the internal implementation instead of using the system security libraries. On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default. To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section. |
