What steps will reproduce the bug?
(continuation of #40814)
I made an snippet that tests RSA key pair generations on every cipher made by crypto.getCiphers(), an fix suggested by #42793 only applies for ECB ciphers, but most cipher variants are still unusable by the same error or variants of it or segfaults
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
});
How often does it reproduce? Is there a required condition?

Additionally, the following ciphers throw an Segmentation fault:
aes128-wrap
aes192-wrap
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)
What is the expected behavior?
An successful encryption/decryption
What do you see instead?
An exception (it varies depending the algorithm used)
For example, when using aes-256-ccm:

Additional information
On my opinion it's still kinda valid? Since this should work by all ciphers detailed by getCiphers()
Sorry in advance if this might not be valid.

Línea de trabajo
Reproduzca los fallos con el script crypto.getCiphers() proporcionado, comenzando en internal/crypto/keygen.js:108, donde generateKeyPairSync informa de los errores. Compare el tratamiento de las clases de cipher enumeradas, especialmente los casos de segmentation fault, y verifique que las entradas compatibles completen el cifrado/descifrado o fallen de forma segura sin bloquearse.
