DecryptAsymmetricEnveloped (Function)

In french: DécrypteAsymétriqueEnveloppé

Warning
From version 28, DecryptAsymmetricEnvelopped is kept for backward compatibility. This function has been replaced with DecryptAsymmetricEnveloped.

Performs the asymmetric encryption of an envelope that has been encrypted with EncryptAsymmetricEnveloped.

Example

// Cryptage d'une chaîne de caractères
//---------------------------------------
bufACrypter is Buffer = "Message à crypter"
bufMessageCrypté is Buffer
sFichierCléPublique is string = fExeDir() + "\ClePublique.pem"
sMotDePasseCléPublique is string = "xxx"

bufMessageCrypté = EncryptAsymmetricEnveloped(bufACrypter, sFichierCléPublique, sMotDePasseCléPublique)

// Décryptage
// -------------
bufMessageCrypté is Buffer
bufMessageDécrypté is Buffer
sFichierCléPrivée is string = fExeDir() + "\ClePrivee.pem"
sMotDePasseCléPrivée is string = "xxx"

bufMessageDécrypté = DecryptAsymmetricEnveloped(bufMessageCrypté, sFichierCléPrivée, sMotDePasseCléPrivée)

bufACrypter is Buffer = "Message à crypter"
bufMessageCrypté is Buffer
bufCléPublique is Buffer
bufCléPrivée is Buffer
(bufCléPrivée, bufCléPublique) = EncryptGenerateRSAKey(1024)
// Cryptage d'une chaîne de caractères
//---------------------------------------
bufMessageCrypté = EncryptAsymmetricEnveloped(bufACrypter, bufCléPublique)

// Décryptage
// -------------
bufMessageCrypté is Buffer
bufMessageDécrypté is Buffer

bufMessageDécrypté = DecryptAsymmetricEnveloped(bufMessageCrypté, bufCléPrivée)

Syntax

<Result> = DecryptAsymmetricEnveloped(<Content to decrypt> , <Private key file> [, <Password>])

<Result>: Buffer

Decrypted content.

<Content to decrypt>: Buffer

Message to decrypt corresponding to the content of EncryptAsymmetricEnveloped.

<Private key file>: Character string or Buffer

Name and path of the file corresponding to the RSA private key to be used to decrypt the data. pem and p12 key formats are supported.
Buffer containing the RSA private key to be used to decrypt the data.

<Password>: Optional character string

Key file password (if required).
