Here is a list of all modules:
[detail level 12]
 Block CiphersBlock ciphers are a n-bit permutation for some small n, typically 64 or 128 bits. It is a cryptographic primitive used to generate higher level operations such as authenticated encryption
 AlgorithmsAlgorithms are meant to provide encryption interface similar to STL algorithms' one
 Exploder functions
 Imploder functions
 Pack functions
 Reverser functions
 Codecs
 AlgorithmsEncoding algorithms are meant to provide encoding interface similar to STL algorithms' one
 Hash Functions & ChecksumsHash functions are one-way functions, which map data of arbitrary size to a fixed output length. Most of the hashes functions in crypto3 are designed to be cryptographically secure, which means that it is computationally infeasible to create a collision (finding two inputs with the same hashes) or preimages (given a hashes output, generating an arbitrary input with the same hashes). But note that not all such hashes functions meet their goals, in particular MD4 and MD5 are trivially broken. However they are still included due to their wide adoption in various protocols
 AlgorithmsAlgorithms are meant to provide hashing interface similar to STL algorithms' one
 Stream CiphersIn contrast to block ciphers, stream ciphers operate on a plaintext stream instead of blocks. Thus encrypting data results in changing the internal state of the cipher and encryption of plaintext with arbitrary length is possible in one go (in byte amounts)
 AlgorithmsAlgorithms are meant to provide decryption interface similar to STL algorithms' one
 Key Derivation FunctionsKey derivation function (KDF) derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function. KDFs can be used to stretch keys into longer keys or to obtain keys of a required format, such as converting a group element that is the result of a Diffie–Hellman key exchange into a symmetric key for use with AES. Keyed cryptographic hash functions are popular examples of pseudorandom functions used for key derivation
 AlgorithmsAlgorithms are meant to provide key derivation interface similar to STL algorithms' one
 Message Authentication CodesA message authentication code (MAC) can be used to verify the integrity of data and the authenticity of a message
