Package-Level Type Names (total 5)

	/* sort by: alphabet | popularity */
	 type Block (struct)
		A Block is an instance of AES using a particular key.
		It is safe for concurrent use.

		Methods (total 3)
			(*Block) BlockSize() int
			(*Block) Decrypt(dst, src []byte)
			(*Block) Encrypt(dst, src []byte)
		Implements (at least one exported)
			*Block : crypto/cipher.Block
		As Outputs Of (at least one exported)
			func New(key []byte) (*Block, error)
		As Inputs Of (at least 11)
			func EncryptionKeySchedule(c *Block) []uint32
			func NewCBCDecrypter(b *Block, iv [16]byte) *CBCDecrypter
			func NewCBCEncrypter(b *Block, iv [16]byte) *CBCEncrypter
			func NewCTR(b *Block, iv []byte) *CTR
			func crypto/internal/fips140/aes/gcm.New(cipher *Block, nonceSize, tagSize int) (*gcm.GCM, error)
			func crypto/internal/fips140/aes/gcm.NewCMAC(b *Block) *gcm.CMAC
			func crypto/internal/fips140/aes/gcm.NewCounterKDF(b *Block) *gcm.CounterKDF
			func crypto/internal/fips140/aes/gcm.NewGCMForSSH(cipher *Block) (*gcm.GCMForSSH, error)
			func crypto/internal/fips140/aes/gcm.NewGCMForTLS12(cipher *Block) (*gcm.GCMForTLS12, error)
			func crypto/internal/fips140/aes/gcm.NewGCMForTLS13(cipher *Block) (*gcm.GCMForTLS13, error)
			func crypto/internal/fips140/aes/gcm.NewGCMWithCounterNonce(cipher *Block) (*gcm.GCMWithCounterNonce, error)

	 type CBCDecrypter (struct)

		Methods (total 3)
			(*CBCDecrypter) BlockSize() int
			(*CBCDecrypter) CryptBlocks(dst, src []byte)
			(*CBCDecrypter) SetIV(iv []byte)
		Implements (at least one exported)
			*CBCDecrypter : crypto/cipher.BlockMode
		As Outputs Of (at least one exported)
			func NewCBCDecrypter(b *Block, iv [16]byte) *CBCDecrypter

	 type CBCEncrypter (struct)

		Methods (total 3)
			(*CBCEncrypter) BlockSize() int
			(*CBCEncrypter) CryptBlocks(dst, src []byte)
			(*CBCEncrypter) SetIV(iv []byte)
		Implements (at least one exported)
			*CBCEncrypter : crypto/cipher.BlockMode
		As Outputs Of (at least one exported)
			func NewCBCEncrypter(b *Block, iv [16]byte) *CBCEncrypter

	 type CTR (struct)

		Methods (total 2)
			(*CTR) XORKeyStream(dst, src []byte)
			(*CTR) XORKeyStreamAt(dst, src []byte, offset uint64)
				XORKeyStreamAt behaves like XORKeyStream but keeps no state, and instead
				seeks into the keystream by the given bytes offset from the start (ignoring
				any XORKetStream calls). This allows for random access into the keystream, up
				to 16 EiB from the start.

		Implements (at least one exported)
			*CTR : crypto/cipher.Stream
		As Outputs Of (at least one exported)
			func NewCTR(b *Block, iv []byte) *CTR
		As Inputs Of (at least one exported)
			func RoundToBlock(c *CTR)

	 type KeySizeError int (basic type)

		Methods (only one)
			( KeySizeError) Error() string
		Implements (at least one exported)
			 KeySizeError : error


Package-Level Functions (total 6)

	 func EncryptionKeySchedule(c *Block) []uint32
		EncryptionKeySchedule is used from the GCM implementation to access the
		precomputed AES key schedule, to pass to the assembly implementation.

	 func New(key []byte) (*Block, error)
		New creates and returns a new [cipher.Block] implementation.
		The key argument should be the AES key, either 16, 24, or 32 bytes to select
		AES-128, AES-192, or AES-256.

	 func NewCBCDecrypter(b *Block, iv [16]byte) *CBCDecrypter
		NewCBCDecrypter returns a [cipher.BlockMode] which decrypts in cipher block
		chaining mode, using the given Block.

	 func NewCBCEncrypter(b *Block, iv [16]byte) *CBCEncrypter
		NewCBCEncrypter returns a [cipher.BlockMode] which encrypts in cipher block
		chaining mode, using the given Block.

	 func NewCTR(b *Block, iv []byte) *CTR
	 func RoundToBlock(c *CTR)
		RoundToBlock is used by CTR_DRBG, which discards the rightmost unused bits at
		each request. It rounds the offset up to the next block boundary.


Package-Level Constants (only one)

	const BlockSize = 16
		BlockSize is the AES block size in bytes.
