Exception when using privateEncrypt/privateDecrypt with certain encrypted keys

Platform

Linux EURO01 5.4.0-88-generic #99-Ubuntu SMP Thu Sep 23 17:29:00 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Subsystem

crypto

What steps will reproduce the bug?

1. Create an public/private RSA key-pair by using either aes-128-ecb or aes-128-ocb
2. Attempt to decrypt/encrypt something

Code:

const crypto = require("crypto");
let {privateKey, publicKey} = crypto.generateKeyPairSync("rsa", {
    modulusLength: 2048,
    publicKeyEncoding: {
        type: "spki",
        format: "pem"
    },
    privateKeyEncoding: {
        type: 'pkcs8',
        format: 'pem',
        cipher: "aes-128-ecb",
        passphrase: "abcdef"
    }
});
const encryptedString = crypto.privateEncrypt({
    key: privateKey,
    passphrase: "abcdef"
}, Buffer.from("The quick brown fox jumps over the lazy dog")).toString("base64");
const decryptedString = crypto.publicDecrypt(publicKey, Buffer.from(encryptedString, "base64")).toString();
console.log(`Encrypted: ${encryptedString}`);
console.log(`Decrypted: ${decryptedString}`);

How often does it reproduce? Is there a required condition?

This only happens with some ciphers, some like aes-128-ccm or aes-128-cbc and other variants works just fine, other ciphers fail with an error

What is the expected behavior?

An successful encryption/decryption with the specified ciphers

What do you see instead?

Additional information

In v14.17.3 (the version i had previously) Node.JS would crash with a core dump on some ciphers (like GCM based ciphers)

Thank you for the report. This is an interesting one. I've been debugging this for a while now and something seems very wrong here.

Most spectacularly, in Node.js 17 (both on Windows and Ubuntu), the first attempt to load an aes-128-ecb encrypted key appears to fail, but the second succeeds:

I'm seeing something similar on node 16.3.1 on Ubuntu 20.04, but with a sightly different error:

}

It doesn't seem to be a first or second call that always fails, I'm getting this both after a successful call and when this is the fist call.
What I have seen is that catching the exception and retrying the call always seems to work.

    try {
        res = crypto.createPrivateKey(key);
    }
    catch(err) {
        console.log("*** FAILED")
        console.error(err)
        try {
            res = crypto.createPrivateKey(key);
        }
        catch(err) {
            console.log("*** FAILED Again")
            console.error(err)
            throw err;
        }        
    }
    return res;
}

Alright, fix seemingly works, but for only ECB ciphers, other ciphers like -ccm -ctr -ocb -xts variants and other cipher types are still broken with more or less the same error... or a variant of it
I used the following snippet to test all ciphers given by crypto.getCiphers()

const crypto = require("crypto");
crypto.getCiphers().forEach((cipherString) => {
    console.log(`Testing: ${cipherString}`);
    if(cipherString == "des3-wrap" || cipherString == "aes128-wrap" || cipherString == "aes192-wrap" || cipherString == "aes256-wrap" || cipherString == "id-aes128-wrap" || cipherString == "id-aes128-wrap-pad" || cipherString == "id-aes192-wrap" || cipherString == "id-aes192-wrap-pad" || cipherString == "id-aes256-wrap" || cipherString == "id-aes256-wrap-pad") {
        console.log(`\x1b[33m[SKIPPED] ${cipherString} due to segmentation fault`);
        console.log("\x1b[37m"); // turn text back to white
        return;
    }
    try {
        let { privateKey, publicKey } = crypto.generateKeyPairSync("rsa", {
            modulusLength: 2048,
            publicKeyEncoding: {
                type: "spki",
                format: "pem"
            },
            privateKeyEncoding: {
                type: 'pkcs8',
                format: 'pem',
                cipher: cipherString,
                passphrase: "abcdef"
            }
        });
        const encryptedString = crypto.privateEncrypt({
            key: privateKey,
            passphrase: "abcdef"
        }, Buffer.from("The quick brown fox jumps over the lazy dog")).toString("base64");
        const decryptedString = crypto.publicDecrypt(publicKey, Buffer.from(encryptedString, "base64")).toString();
        console.log(`\x1b[32m[PASS]`);
        console.log(`Encrypted: ${encryptedString}`);
        console.log(`Decrypted: ${decryptedString}`);
    } catch(err) {
        console.log(`\x1b[31m[FAILED] ${err.stack}`);
    }
    console.log("\x1b[37m"); // turn text back to white
});

Additionally, the following ciphers throw an Segmentation fault:

aes256-wrap
id-aes128-wrap
id-aes128-wrap-pad
id-aes192-wrap
id-aes192-wrap-pad
id-aes256-wrap
id-aes256-wrap-pad

With the exception of des3-wrap who fails with error:1C800066:Provider routines::cipher operation failed before throwing the following as I try a few more times to encrypt:

corrupted size vs. prev_size
Aborted (core dumped)

Versions i tried:

• v20.0.0-nightly2022110286088ab78e
• v20.0.0-nightly20221101590cf569fe

I'm not really sure if these would apply for an separate issue, or it should be an continuation of this issue... or even if it should be valid, in my opinion it is since I would expect this to work with all ciphers at crypto.getCiphers() at least.

@PANCHO7532B you should probably open a new issue, or a directly a PR if you know what is the fix.
