(PHP ActiveX) Decrypt MIME using RSAES-OAEP with SHA256 and AES-128 content encryptionDemonstrates how to decrypt MIME what was encrypted with RSAES-OAEP with SHA256 and AES-128 content encryption. In actuality, we don't really need to know in advance the various algorithms used to encrypt the MIME. When decrypting, the information about the algorithms required are embedded in the PCKS7 message itself, and this tells a decryptor what it should use. Note: This example requires Chilkat v9.5.0.67 or greater.
