CKR_BUFFER_TOO_SMALL

[JoeKolba]

This might not be an issue, but I keep running into this problem. I am using graphene with Vormetric Data Security Manager. I am able to connect to the pkcs11 agent, create an encryption key and encrypt data. However every time I try to decrypt I get the following:

CKR_BUFFER_TOO_SMALL

graphene-pk11/build/crypto/decipher.js:25:32

  Decipher.prototype.update = function (data) {
        try {
            var len = Math.ceil(data.length / this.blockSize) * this.blockSize;
            var dec = new Buffer(len);
            var res = this.lib.C_DecryptUpdate(this.session.handle, data, dec);
            return res;
        }
        catch (e) {
            try {
                this.final();
            }
            catch (e) { }
            throw e;
        }
    };

I believe this was a problem in the past that was already solved. I think it had to do with the calculation of the length. If anyone could help I would appreciate it.

Could you make a log for incoming data and get data.length, this.blockSize and mechanism you use, if it's possible
