[C language] MD5 encryption for account password

The source code parsing

//md5 Encrypt user password 
UtlMd5_t ctx;
unsigned char serverDigest[16];
utl_md5_init(&ctx);
//md5 initialization 
utl_md5_update(&ctx, "admin", strlen("admin"));
// Pass the encrypted information to the initialized MD5 Structure , No return value 
// Cross account 
utl_md5_update(&ctx, "debug_get_vs_status", strlen("debug_get_vs_status"));
// Transmit control instructions 
utl_md5_update(&ctx, "admin123", strlen("admin123"));
// Pass the code 
utl_md5_final(&ctx, serverDigest);
// convert to 32 Bit 16 Base string 
int i=0;
unsigned char decrypt32[64]={
    0};
char temp[8]={
    0};

for(i=0;i<16;i++)
{
    
	sprintf(temp,"%02x",serverDigest[i]);// Convert hex to string %x=0x6b ==> %s="6b"
	strcat((char *)decrypt32,temp);
}
// Last generated decrypt32 That is to say md5 Encrypted password ："6be7c69c5cdf177753270cf390ef1e90"
