Update the following to sections in your composer file:

   "require": {
           "proxiblue/recaptcha":"*"

Clear Cache
Enable compilation

Setup:

Obtain your site public key (Site Key) and private key (Secret Key) for your domain and recaptcha usage
Enter these in the admin settings for captcha.

Making captcha work in magento 1.9 (RWD theme)

Captcha was disabled in the RWD theme that magento 1.9 uses.

This was done by simply placing an empty layout xml file into the theme.

To make captcha work in magento 1.9:

Place a copy of the base captcha.xml file into your own theme layout folder.

cp app/design/frontend/base/default/layout/captcha.xml app/design/frontend/YOUR_PACKAGE/THEME/layout/captcha.xml
or, delete that file from the rwd theme to fallback to base,

rm app/design/frontend/rwd/default/layout/captcha.xml

Contact Us Captcha

Enable in admin under Customer Configuration by selecting COntacts in available forms list
Unfortunately the core contact us form does not have before or after form elements block, so you will need to adjust your contact us form to display the capctha.

Edit the contact form located here:

app/design/frontend/[rwd|base|your package]/[default|your theme]/template/contacts/form.phtml

place the following line into the form, anywhere between the form elements.

<?php echo $this->getChildHtml('recaptcha'); ?>

Unfortunately magento core templates do not accomodate reloading the posted form data. This means that if the captcha was incorrect, the user will be given a new blank form. Obviously not ideal.

The captcha extension places the form data into the customer session, aptly named 'formData', using the following lines of code

$data = $controller->getRequest()->getPost();
Mage::getSingleton('customer/session')->setFormData($data);

You can re-populate the form data using the information stored in the session. This will require you to make some changes to the form.phtml file. It is really up to you how you will retrieve and use the session data. As an example, you can do this at the top of the template form.phtml:

$formData = new Varien_Object();
$formData->setData(Mage::getSingleton('customer/session')->getFormData());

The posted data is now held in the Varien Object called $formData You can pre-populate the data as such:

$_firstname = ($formData->getFirstname())?$formData->getFirstname():$this->helper('contacts')->getFirstName();
$_lastname = ($formData->getLastname())?$formData->getLastname():$this->helper('contacts')->getLastName();
$_email = ($formData->getEmail())?$formData->getEmail():$this->helper('contacts')->getEmail();
$_telephone = ($formData->getTelephone())?$formData->getTelephone():'';
$_suburb = ($formData->getSuburb())?$formData->getSuburb():'';  
$_postcode = ($formData->getPostcode())?$formData->getPostcode():'';
$_comment = ($formData->getComment())?$formData->getComment():'';

and in the template, simply echo out the values held in the definded variables: An example is as such:

<input name="firstname" id="firstname" title="<?php echo Mage::helper('contacts')->__('First Name') ?>" value="<?php echo $this->htmlEscape($_firstname) ?>" class="input-text required-entry" type="text" />

Product Review Captcha

Enable in admin under Customer Configuration by selecting 'reviews' in available forms list
Unfortunately the core product review form does not have an after form elements block, so you will need to adjust your reviews form to display the captcha.

Edit the reviews form located here:

app/design/frontend/[rwd|base|your package]/[default|your theme]/template/review/form.phtml

place the following line into the form, anywhere between the form elements.

<?php echo $this->getChildHtml('recaptcha'); ?>

Captcha is still not appearing, even after I did the steps above!

Some possibilities:

You are using a custom theme package, and the reCaptcha layout directive file is not loaded.
You are using a custom theme and the fallback to the base theme is not picking up the layout file.

To fix this, simply copy the file app/design/frontend/base/default/layout/proxiblue_recaptcha.xml to your package or theme folder, which will be located something like such: app/design/frontend/<PACKAGE_NAME>/<THEME NAME>/layout/proxiblue_recaptcha.xml

You have directives in your custom theme that changes how the review and customer screen layouts are built.

There can be quite a few ways that your custom theme/package changed this. The most common would be in your local.xml file, located at app/design/frontend/<PACKAGE_NAME>/<THEME NAME>/layout/local.xml In that file, locate the relevant sections as noted in the reCaptcha layout file (https://github.com/ProxiBlue/reCaptcha/blob/master/app/design/frontend/base/default/layout/proxiblue_recaptcha.xml) Insert into the layout sections the relevant reCaptcha parts.

For example, if you have this section in your lcoal.xml file

<review_product_list>
</review_product_list>

copy the entire section from the reCaptcha layout over into that section.

<reference name="product.review.form">
            <block type="captcha/captcha" name="recaptcha">
                <action method="setFormId">
                    <formId>user_review</formId>
                </action>
                <action method="setImgWidth">
                    <width>230</width>
                </action>
                <action method="setImgHeight">
                    <width>50</width>
                </action>
            </block>
        </reference>
</review_product_list>

If, you also have the following: <reference name="product.review.form"> then only copy the BLOCK definition part into that reference.
