Cryptography
The Wolfram Language includes built-in functions for both symmetric (private-key) and asymmetric (public-key) cryptography, including RSA, elliptic curve and other methods.
Encryption & Decryption
Encrypt — encrypt any expression with symmetric or asymmetric encryption
Decrypt — decrypt an encrypted object or byte array
Representation of Encrypted Data
EncryptedObject — symbolic representation of encrypted data and related metadata
ByteArray — raw bytes of ciphertext etc.
File Encryption
EncryptFile, DecryptFile — encrypt, decrypt files and cloud objects
Encryption System Specification
SymmetricKey — key giving complete information for a symmetric encryption system
PublicKey — public key for an asymmetric (public-key) encryption system
PrivateKey — private key for an asymmetric (public-key) encryption system
Key Generation
GenerateSymmetricKey — generate a key randomly or from a password
GenerateAsymmetricKeyPair — generate random public and private keys
Key Derivation
GenerateDerivedKey — derive a key from a password (using scrypt, etc.)
VerifyDerivedKey — verify a password from a derived key
DerivedKey — representation of a derived key
Key Management
Import, ImportString — import keys from "PEM" files
SecurityCertificate — representation of a public-key security certificate
Digital Signatures
GenerateDigitalSignature — generate a digital signature using a private key
VerifyDigitalSignature — verify a digital signature using a public key
DigitalSignature — symbolic representation of a digital signature
Hash — compute a wide range of cryptographic hashes
