I generated a keystore using Thorswap, and I noticed that it uses the 'xchain-crypto' JS library to generate the keystore file. The generated keystore file looks very similar to Ethereum's keystore format（Ethereum Wallet, PBKDF2-HMAC-SHA256 15600）, with the method set to 15600. However, when I try to decrypt it, I get a 'Token length exception' error. It seems that the ciphertext field's length is not fixed, while the format defined in the 'module_15600.c' file specifies ciphertext a fixed length of 64. Can anyone support this keystore format, or how can I modify it to decrypt the password?
