This doesn't seem like it needs to be a class anymore, now that the iterator
interface is cleaned up and no friends are used

(the protobuf class) SerializeCertVerifierCache(const CachingCertVerifier&
verifier);

(void/bool?) DeserializeCertVerifierCache(const TheProtobufClass&,
CachingCertVerifier* verifier);

Done.

+ public:
+  CertVerifierCachePersister(CachingCertVerifier* verifier);

STYLE: Explicit

Deleted the class.

+  ~CertVerifierCachePersister();
+
+  // Recursively iterate over this |verifier_|'s |cache_| and all children and
+  // write the hierarchical structure into |data|.

|cache_| is not a recursive structure.

Also, you're talking about implementation details. You're not accessing
|cache_|, you're accessing it's iterator. Talk in terms of public interfaces

// Iterates through |verifier_|'s cache and serializes the data to |data|. This
can be used to populate a new CachingCertVerifier with
// |LoadCache()|

[ramant (doing other things), 2016/06/09 00:51:39]

Done.

+  void SerializeCache(std::string* data);
+
+  // Populates CachingCertVerifier's |cache_|. Returns true if the |data| is
+  // deserialized correctly.
+  bool LoadCache(const std::string& data);
+
+ private:
+  // |verifier_| whose |cache_| will be serialized/deserialized.
+  CachingCertVerifier* verifier_;  // Owned by the caller.
