endless recursion

[itaymigdal]

hey, I have a super weird bug, I wrote two functions: encrypt_cbc and decrypt_cbc - they both get (string, key, iv) and do their job great. Whenever I'm importing winim/clr to the program (Winim) - context.init(key, iv) calls the clr which invokes an endless recursion, which crashes the program.. the functions:

proc encrypt_cbc(plain_text: string, key: string, iv: string): string =
    var ectx: CBC[aes256]
    var cipher_text = newString(aes256.sizeBlock * 2)
    var plain_text_padded = plain_text
    while len(plain_text_padded) mod 32 != 0:
        plain_text_padded = plain_text_padded & " "
    ectx.init(key, iv)
    ectx.encrypt(plain_text_padded, cipher_text)
    ectx.clear()
    return cipher_text

proc decrypt_cbc(cipher_text: string, key: string, iv: string): string =
    var dctx: CBC[aes256]
    var plain_text = newString(aes256.sizeBlock * 2)
    dctx.init(key, iv)
    dctx.decrypt(cipher_text, plain_text)
    dctx.clear()
    while plain_text.endsWith(" "):
        plain_text.removeSuffix(" ")
    return plain_text

thanks in advance, Itay
