Buderus KM200 api

[sds]

Hi all

Just upgraded from 20230607 to 20240426 version, with error message

Code:

User library aes:185: Symbol not found: EVP_CIPHER_CTX_block_size
stack traceback:
[C]: in function '__index'
User library aes:185: in function 'new'
User script:107: in function 'km200_GetData'

I updated aes.lua as suggested in https://forum.logicmachine.net/showthrea...9#pid34799

However, I stumble now to another error (while the Buderus REST API did not change)

Reading the output of the error message thrown by aes decrypt function

Code:

local res, err2 = aes_256_ecb:decrypt(encdec.base64dec(decryptData)) -- data block size is always 128 bits
  alert (err2)

resulted in: "EVP_DecryptFinal_ex failed"

Which is thrown by following code

Code:

    if C.EVP_DecryptFinal_ex(ctx, buf + out_len[0], tmp_len) == 0 then
        return nil, "EVP_DecryptFinal_ex failed"
    end

Any suggestion? What info is needed to debug further?
