Chrome memory leak with pkcs7.encrypt and big files (>160MB)?

[bauesch]

Hi folks,
I am using forge's pkcs#7 encryption which is actually working fine :-)

The following code works in Firefox for filesizes up to 500MB + maybe more (not tested for bigger files than that).
But Chrome allocates much more memory than FF and crashes due to out of memory exceptions with a file size of 167MB already! Tested with latest Chrome (78.0.3904.97) on Windows 10 64 Bit .

Can anyone help?
Thanks in advance!

Here is the code:

var reader = new FileReaderSync();
var encryptedData = createPKCS7(reader.readAsBinaryString(file),global_certData);
            
// buffer: File as binary string
function createPKCS7(buffer, certData)
{
	// create enveloped data
	var p7 = forge.pkcs7.createEnvelopedData();
	// add certificate of pkcs#12 as recipient
	p7.addRecipient(certData.cert);
	// set content
	p7.content = forge.util.createBuffer(buffer);
	// encrypt
	p7.encrypt();  // crashes with chrome & big files
	// convert to Der format
	var p7Der = forge.asn1.toDer(p7.toAsn1());
	return forge.util.binary.raw.decode(p7Der.getBytes()); //return pkcs7Der
}

@bauesch did you solve somehow?
I faced the same problem...
