error 🔒

Structs

Aad

The additionally authenticated data (AAD) for an opening or sealing operation. This data is authenticated but is not encrypted.

EncryptError

Why encrypt could not seal a plaintext.

EncryptionKeyError

Why get_encryption_key could not derive a key: Argon2 rejected the password or the salt, such as a salt that is too short.

LessSafeKey

Immutable keys for use in situations where OpeningKey/SealingKey and NonceSequence cannot reasonably be used.

UnboundKey

An AEAD key without a designated role or nonce sequence.

Enums

DecryptError

Why decrypt could not open a ciphertext.

EncryptedReadError

Why encrypted_read could not read a file.

EncryptedWriteError

Why encrypted_write could not write a file.

Constants

NONCE_LEN

All the AEADs we support use 96-bit nonces.

Functions

argon2 🔒

Constructs Argon2 with default params, easier if the weak crypto flag is set for testing

decrypt

Decrypts a ciphertext using key.

encrypt

Encrypt plaintext using key.

encrypted_read

Reads encrypted data from a file

encrypted_write

Write data encrypted to a file with a random nonce that will be encoded in the file

get_encryption_key

Key used to encrypt and authenticate data stored on the filesystem with a user password.

get_random_nonce

Get a random nonce.

random_salt

Generates a B64-encoded random salt string of the recommended 16 byte length
