the "example" code to decrypt the content data:
Code:

#include <stdio.h>
#include <stdlib.h>
#include <tomcrypt.h>

int ts3_content_decrypt(unsigned char *tmpkey, unsigned char *data, int datalen) {
    symmetric_CTR   ctr;
    int             cipher_idx,
                    hash_idx,
                    ks;
    long            outlen;
    unsigned char   key[MAXBLOCKSIZE];

    register_hash(&sha512_desc);
    hash_idx = find_hash("sha512");
    if(hash_idx < 0) return(-1);

    register_cipher(&aes_desc);
    cipher_idx = find_cipher("aes");
    if(cipher_idx < 0) return(-1);

    ks = hash_descriptor[hash_idx].hashsize;
    if(cipher_descriptor[cipher_idx].keysize(&ks) != CRYPT_OK) return(-1);

    outlen = sizeof(key);
    if(hash_memory(
        hash_idx,
        tmpkey,
        strlen((char *)tmpkey),
        key,
        &outlen) != CRYPT_OK) return(-1);

    if(ctr_start(
        cipher_idx,
        key + ks,
        key,
        ks,
        0,
        CTR_COUNTER_LITTLE_ENDIAN,
        &ctr) != CRYPT_OK) return(-1);

    if(ctr_decrypt(
        data,
        data,
        datalen,
        &ctr) != CRYPT_OK) return(-1);

    return(0);
}

// example of TeamSpeak 3 ts3clientui_qt.secrets.conf "content" decrypter
int main(int argc, char *argv[]) {
    #define salt    "mnJ0C3CXOlkPshg7YHVXyA=="  // the salt string as is

    unsigned char   content[] =                 // the content's decoded base64 data
                    "put the decoded base64 data of content";
    int             content_len = sizeof(content) - 1;

    ts3_content_decrypt(salt key, content, content_len);
    fwrite(content, 1, content_len, stdout);
    return(0);
}
