    I did not understand, can you go more into detail?
    Julius Mereckas
    @mereckaj
    Sure
    If I try to sign a message digest using ECDSA, and I use sjcl.ecc.curves.c521 when trying to verify message integrity I keep getting an error of "Cannot assign to read only property '7' of lkQZDJh9". This only happens with c521 and k224. But k224 is known to be broke (according to issue 262). I am wondering if c521 is broken too
    Nils Thenhausen
    @Nilos
    if that is what happens it looks like it :(
    will have a look tomorrow, is late at my location :)
    Julius Mereckas
    @mereckaj
    Cool, thanks :D I'll try and find the problem myself too
    Julius Mereckas
    @mereckaj
    Ah so turns out it was my mistake, sign expects a bitArray and I was passing it strings. Worked file for all but the c521 curve strangely enough.
    file -> fine

    hey
    guys
    I need help, whats the default bit size for of Crypto-JS lib? is it 256 or 128?
    Nils Thenhausen
    @Nilos
    I don't know. This is the sjcl chat, so I guess we might not be able to help you, sorry!

    Hi, just downloaded sjcl, looking for ecc functionality. Is this lib still in use? Is the ecc stuff working?

    @tiredoak
    Hi, in the same situation as @tunkul. Anyone around still?
    @Nilos ?
    Nils Thenhausen
    @Nilos
    ECC is working but you will need to build your own version for it
    I am still around even though gitter stopped sending me mails for chat-messages
    See https://github.com/bitwiseshiftleft/sjcl/wiki/Asymmetric-Crypto

    Hi all,
    Is it possible to generate symmetric keys using the sjcl library?
    Nils Thenhausen
    @Nilos
    Sure!
    Nils Thenhausen
    @Nilos
    const key = sjcl.random.randomWords(8)(for a 256-bit key)

    Hello, quick question:
    The readme specifies the security reporting email as sjcl@ovt.me, yet the website at ovt.me seems a little (read: very) odd.
    I don’t have anything to report, but just wanted to make sure that the email wasn’t a typo or anything :P
    Nils Thenhausen
    @Nilos
    Not sure why my website seems odd to you :D It is just a very old side project of mine
    Aaron Janse
    @aaronjanse
    Oh, no problem! :D I guess I was just thrown off by the "Welcome to vokabelnpauken.de" heading. Np. The project looks cool, btw; I don't speak German, but from what I can tell it looks interesting.

    @Nilos
    It is indeed really old but I still use the address for my mail

    Hi,

    I know I can encrypt a string using a password with sjcl.encrypt() and decrypt using sjcl.decrypt(), but can I just verify the password to decrypt a string is correct first so then if it is correct, I can go ahead and decrypt and if it's not, I go ahead and spit out an error message?

    Thanks.

    Nils Thenhausen
    @Nilos
    No you can't. A password is only known to be incorrect after the decryption process has happened and the data after decryption does not validate.
    Or to say it differently: any password gives a decryption result but only the correct password yields one that makes sense

    Hi, can anyone help me out with https://github.com/mdp/gibberish
    when try to encrypt a text, it returns me a plain string with random characters instead of a JSON string
    cipher = Gibberish::AES.new('p4ssw0rd')
    cipher.encrypt("some secret text")

    => Outputs a JSON string containing everything that needs to be saved for future decryption

    Example:

    '{"v":1,"adata":"","ks":256,"ct":"ay2varjSFUMUmtvZeh9755GVyCkWHG0/BglJLQ==","ts":96,"mode":"gcm",

    "cipher":"aes","iter":100000,"iv":"K4ZShCQGL3UZr78y","salt":"diDUzbc9Euo="}'

    @john007abhilash
    sjcl.decrypt does not work as it needs the json to decrypt it

    Hey guys, I'll need to save some sensitive data on client side in localstorage.

    I've been wondering what's the best I can do about that and sjcl seems to be a good idea.

    I know there's no perfect security, I just want to do the best possible :)

    That said, is sjcl.encrypt enough? Is there a better configuration to make it harder to brute force or find with other ways?

    @sechel
    Hey @maxime1992, you may want to check out WebCrypto and IndexedDB as an alternative to sjcl and localStorage.

    @christinasmithers
    Hi everyone. I admit I am little of a newbie for security. Does SJCL issue certificates and if so from whom? And then for keys do we keep or maintain them or is that elsewhere?

    @yeshog
    hello all, how does one get to use sjcl out of the box i.e. without needing to use "configure --with-all" out of the box? A typical use of this is PaaS cloud environments where one needs to simply supply a dependency in package.json?

    Hello there
    how can we use sjcl.js on a static webpage? Can anyone help me out? I have read the documentation, but still have no clue

    does anyone know what encryption lib creates output like this? -- var _0x28b6=['VcOfwq/DlMOM','BsOeZcKGw4s=','wqEwwpULFxE=','bGPDh8OWMA==','OcO9acKDw6c='
    It seems to be creating a massive array of base64 strings

    @abdulrabbt

    Hi all,
    I use this function to generate a key "AES-GCM" and how I can generate the same algorithm with the sjcl ?

    const generateKey = async () => {
    const key = await window.crypto.subtle.generateKey({ name: "AES-GCM", length: 128 }, true, ["encrypt", "decrypt"]);
    const key_exported = await window.crypto.subtle.exportKey("jwk", key);
    return key_exported.k;
    };
