+# NAME
+
+CURLOPT_CAINFO_BLOB - Certificate Authority (CA) bundle in PEM format
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAINFO_BLOB,
+                          struct curl_blob *stblob);
+~~~
+
+# DESCRIPTION
+
+Pass a pointer to a curl_blob structure, which contains information (pointer
+and size) about a memory block with binary data of PEM encoded content holding
+one or more certificates to verify the HTTPS server with.
+
+If the blob is initialized with the flags member of struct curl_blob set to
+CURL_BLOB_COPY, the application does not have to keep the buffer around after
+setting this.
+
+If CURLOPT_SSL_VERIFYPEER(3) is zero and you avoid verifying the
+server's certificate, CURLOPT_CAINFO_BLOB(3) is not needed.
+
+This option overrides CURLOPT_CAINFO(3).
+
+# DEFAULT
+
+NULL
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+#include <string.h>
+
+int main(void)
+{
+  char *strpem = "PEMDATA"; /* strpem must point to a PEM string */
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    struct curl_blob blob;
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
+    blob.data = strpem;
+    blob.len = strlen(strpem);
+    blob.flags = CURL_BLOB_COPY;
+    curl_easy_setopt(curl, CURLOPT_CAINFO_BLOB, &blob);
+    res = curl_easy_perform(curl);
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# HISTORY
+
+This option is supported by the mbedTLS (since 7.81.0), Rustls (since 7.82.0),
+wolfSSL (since 8.2.0), OpenSSL and Schannel backends.
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
