Crate tink_aead

Provides implementations of the AEAD primitive.

AEAD encryption assures the confidentiality and authenticity of the data. This primitive is CPA secure.

Modules

subtle

Provides subtle implementations of the tink_core::Aead primitive.

Structs

KmsEnvelopeAead

KmsEnvelopeAead represents an instance of Envelope AEAD.

Functions

aes128_ctr_hmac_sha256_key_template

Return a KeyTemplate that generates an AES-CTR-HMAC-AEAD key with the following parameters:

aes128_gcm_key_template

Return a KeyTemplate that generates an AES-GCM key with the following parameters:

aes128_gcm_siv_key_template

Return a KeyTemplate that generates an AES-GCM-SIV key with the following parameters:

aes256_ctr_hmac_sha256_key_template

Return a KeyTemplate that generates an AES-CTR-HMAC-AEAD key with the following parameters:

aes256_ctr_hmac_sha512_key_template

Return a KeyTemplate that generates an AES-CTR-HMAC-AEAD key with the following parameters:

aes256_gcm_key_template

Return a KeyTemplate that generates an AES-GCM key with the following parameters:

aes256_gcm_no_prefix_key_template

Return a KeyTemplate that generates an AES-GCM key with the following parameters:

aes256_gcm_siv_key_template

Return a KeyTemplate that generates an AES-GCM-SIV key with the following parameters:

aes256_gcm_siv_no_prefix_key_template

Return a KeyTemplate that generates an AES-GCM-SIV key with the following parameters:

cha_cha20_poly1305_key_template

Return a KeyTemplate that generates a CHACHA20_POLY1305 key.

init

Initialize the tink-aead crate, registering its primitives so they are available via tink-core.

kms_envelope_aead_key_template

Return a KeyTemplate that generates a KmsEnvelopeAead key for a given KEK in remote KMS. Keys generated by this key template uses RAW output prefix to make them compatible with the remote KMS’ encrypt/decrypt operations. Unlike other templates, when you generate new keys with this template, Tink does not generate new key material, but only creates a reference to the remote KEK.

new

Returns a tink_core::Aead primitive from the given keyset handle.

x_cha_cha20_poly1305_key_template

Return a KeyTemplate that generates a XCHACHA20_POLY1305 key.
