KSMIMECrypto::rc KSMIMECrypto::checkDetachedSignature	(	const QByteArray &	clearText,
		const QByteArray &	signature,
		QList< KSSLCertificate * > &	foundCerts
	)

Check a detached message signature Will check if messages matches signature and extract certificates Does not check certificates for validity!

Parameters

clearText	MIME representation of signed message (without SIG)
signature	signature
foundCerts	certificates found in this message

Returns

0 on success

Definition at line 331 of file ksmimecrypto.cpp.

KSMIMECrypto::rc KSMIMECrypto::checkOpaqueSignature	(	const QByteArray &	signedText,
		QByteArray &	clearText,
		QList< KSSLCertificate * > &	foundCerts
	)

Check an opaque signed message Will check if signature matches and extract message Does not check certificates for validity!

Parameters

signedText	signed message block
clearText	cleartext of signed message
foundCerts	certificates found in this mesasge

Returns

0 on success

Definition at line 351 of file ksmimecrypto.cpp.

KSMIMECrypto::rc KSMIMECrypto::decryptMessage	(	const QByteArray &	cipherText,
		QByteArray &	clearText,
		const KSSLPKCS12 &	privKey
	)

Decrypt a message.

Parameters

cipherText	encrypted message block
clearText	returns decrypted message
privKey	private key to use

Returns

0 on success

Definition at line 400 of file ksmimecrypto.cpp.

KSMIMECrypto::rc KSMIMECrypto::encryptMessage	(	const QByteArray &	clearText,
		QByteArray &	cipherText,
		algo	algorithm,
		const QList< KSSLCertificate * > &	recip
	)

Encrypt a message encrypts a message for the given list of recipients and the selected algorithm.

Note that any algorithm <128 bytes is insecure and should never be used, even if SMIME-2 requires only RC2-40

Parameters

clearText	MIME representation of message to encrypt
cipherText	returned encrypted message
algorithm	encryption algorithm
recip	recipient certificates

Returns

0 on success

Definition at line 375 of file ksmimecrypto.cpp.

KSMIMECrypto::rc KSMIMECrypto::signMessage	(	const QByteArray &	clearText,
		QByteArray &	cipherText,
		const KSSLPKCS12 &	privKey,
		const QList< KSSLCertificate * > &	certs,
		bool	detached
	)

Sign a message.

Parameters

clearText	MIME representation of the message (part) to sign
cipherText	signature to append or signature block
privKey	private key/certificate to sign with
certs	additional certificates (may be empty)
detached	create detached or opaque signature

Returns

0 on success
