DecryptAsymmetricEnveloped (Function)

In french: DécrypteAsymétriqueEnveloppé

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

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

Example

// Encrypting a character string
//---------------------------------------
bufToEncrypt is Buffer = "Message to encrypt"
bufEncryptedMessage is Buffer
sPublicKeyFile is string = fExeDir() + "\PublicKey.pem"
sPublicKeyPassword is string = "xxx"

bufEncryptedMessage = EncryptAsymmetricEnveloped(bufToEncrypt, sPublicKeyFile, ...
sPublicKeyPassword)

// Decryption
// -------------
bufEncryptedMessage is Buffer
bufDecryptedMessage is Buffer
sPrivateKeyFile is string = fExeDir() + "\PrivateKey.pem"
sPrivateKeyPassword is string = "xxx"

bufDecryptedMessage = DecryptAsymmetricEnveloped(bufEncryptedMessage, sPrivateKeyFile, ...
sPrivateKeyPassword)

New in version 28

bufToEncrypt is Buffer = "Message to encrypt"
bufEncryptedMessage is Buffer
bufPublicKey is Buffer
bufPrivateKey is Buffer
(bufPrivateKey, bufPublicKey) = EncryptGenerateRSAKey(1024)
// Encrypting a character string
//---------------------------------------
bufEncryptedMessage = EncryptAsymmetricEnveloped(bufToEncrypt, bufPublicKey)

// Decryption
// -------------
bufEncryptedMessage is Buffer
bufDecryptedMessage is Buffer

bufDecryptedMessage = DecryptAsymmetricEnveloped(bufEncryptedMessage, bufPrivateKey)

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.
New in version 28
Buffer containing the RSA private key to be used to decrypt the data.

<Password>: Optional character string

Key file password (if required).
