All Classes and Interfaces

Class	Description
Base32Codec	A byte-to-text-safe-byte transform using Base32 (RFC 4648 §6) or its "extended hex" variant (RFC 4648 §7).
Base64Codec	A byte-to-text-safe-byte transform: encodes any bytes as Base64 (RFC 4648) and decodes them back.
BoundedDataKeyStrategy	Opt-in DataKeyStrategy that caches a data-encryption key (DEK) and rolls to a fresh one after maxMessages messages or maxAge has elapsed, whichever comes first.
ChecksumCodec	A Codec<byte[]> transform that appends a 32-bit checksum (big-endian) on encode and verifies it on decode, rejecting a mismatch with IllegalArgumentException.
Codec<T>	Converts values of type T to and from byte[].
CodecDeserializer<T>	Adapts a Codec to Kafka's Deserializer.
CodecFactory	Produces Codec instances for arbitrary types, backed by a serialization library.
CodecRedisCacheAutoConfiguration	Serializes Redis cache values through the application's CodecFactory.
CodecRedisCacheProperties	Settings for serializing Redis cache values through the application's CodecFactory.
CodecRedisSerializer<T>	Adapts a Codec to Spring Data Redis's RedisSerializer, so a codec — with whatever compression or encryption it composes — is what Redis stores: RedisTemplate<String, Person> template = new RedisTemplate<>(); template.setValueSerializer(CodecRedisSerializer.of(factory, Person.class));
CodecSerde<T>	A Kafka Serde pairing a CodecSerializer and CodecDeserializer over one codec, for Kafka Streams: KStream<String, Person> people = builder.stream("people", Consumed.with(Serdes.String(), new CodecSerde<>(codec)));
CodecSerializer<T>	Adapts a Codec to Kafka's Serializer.
CompressionStreamCodec	Base class for stream-based compression transforms, intended for use with Codec.andThen(Codec).
DataKey	A data-encryption key (DEK) acquired from a DataKeyProvider: the plaintext key material used to encrypt or decrypt one message, paired with the id of the key-encryption key (KEK) that wrapped it and the wrapped (ciphertext) form of the key itself.
DataKeyProvider	SPI for envelope-encryption key management, implemented by consumers against an in-process key store or a remote KMS (AWS KMS, HashiCorp Vault, GCP Cloud KMS, etc.).
DataKeyStrategy	Pure lifecycle policy for acquiring the data-encryption key used to encode a message.
DecryptionException	Exception indicating that the data provided for decryption is invalid or corrupted.
DeflateCodec	Compresses with the zlib format (RFC 1950): DEFLATE data wrapped in a two-byte header and Adler-32 checksum.
DirectDataKeyStrategy	Default DataKeyStrategy: acquires a fresh data-encryption key per message.
EncryptionException	Exception indicating a failure during the encryption operation.
EnvelopeCodec	Envelope-encryption Codec for byte[]: encrypts with AES-256-GCM under a per-message data-encryption key (DEK), itself wrapped by a DataKeyProvider and carried alongside the ciphertext.
EnvelopeCodec.Builder	Builder for EnvelopeCodec.
ForyCodecAutoConfiguration	Registers a ForyCodecFactory when the application defines a ThreadSafeFory bean.
ForyCodecFactory	A CodecFactory backed by Apache Fory: fast binary serialization for JVM-to-JVM payloads such as cache entries, queue messages and journal records.
GsonCodecAutoConfiguration	Auto-configures a GsonCodecFactory when the Gson backend is on the classpath and no other CodecFactory bean exists.
GsonCodecFactory	Produces JSON codecs backed by a shared Gson instance.
GzipCodec	Compresses with the gzip format (RFC 1952): DEFLATE data wrapped in a gzip header and CRC-32 trailer.
HexCodec	A byte-to-text-safe-byte transform using hexadecimal (RFC 4648 base16): two ASCII digits per input byte.
Jackson2CodecAutoConfiguration	Auto-configures a Jackson2CodecFactory when the Jackson 2.x backend is on the classpath and no other CodecFactory bean exists.
Jackson2CodecFactory	Produces JSON codecs backed by a shared Jackson 2.x ObjectMapper.
JacksonCodecAutoConfiguration	Auto-configures a JacksonCodecFactory when the Jackson 3.x backend is on the classpath and no other CodecFactory bean exists.
JacksonCodecFactory	Produces JSON codecs backed by a shared Jackson 3.x ObjectMapper.
JceDataKeyProvider	In-process DataKeyProvider for consumers without a KMS, backed by one or more key-encryption keys (KEKs) supplied at construction.
JceDataKeyProvider.Builder	Builder for JceDataKeyProvider.
JsonbCodecAutoConfiguration	Registers a JsonbCodecFactory when the JSON-B backend and API are on the classpath and no other backend has claimed the CodecFactory slot.
JsonbCodecFactory	A CodecFactory backed by Jakarta JSON Binding (JSON-B).
KeyAccessException	Exception indicating that key infrastructure is unavailable.
Lz4Codec	LZ4 compression as a Codec<byte[]> transform, for use with Codec.andThen.
ProtobufCodecAutoConfiguration	Auto-configures a ProtobufCodecFactory when the Protocol Buffers backend is on the classpath and no other CodecFactory bean exists.
ProtobufCodecFactory	Produces codecs for Protocol Buffers messages (GeneratedMessage subclasses), using each message type's own Parser.
StringCodec	A Codec<String> whose bytes are simply the text in a charset — no quoting, no framing.
TypeRef<T>	Super type token capturing a full generic type at compile time, surviving erasure.
ZstdCodec	Zstandard (RFC 8878) compression as a Codec<byte[]> transform, for use with Codec.andThen.
