Detailed Description

Liquid Crypto Feature Parameters.

This structure is used to store the feature parameters of the liquid crypto device. The feature parameters are used to calculate the size of the maximum segment size.

Field Documentation

cipher_auth_payload_len

uint16_t cipher_auth_payload_len

Cipher and auth payload length.

• Cipher only: length of cipher text.
• Auth only: length of data to be authenticated.
• Cipher and auth: length of data with possible overlap.
• AEAD: length of data for authenticated encryption.

Definition at line 525 of file dao_liquid_crypto.h.

iv_len

uint16_t iv_len

IV length

Definition at line 527 of file dao_liquid_crypto.h.

aad_len

uint16_t aad_len

AAD length

Definition at line 529 of file dao_liquid_crypto.h.

digest_len

uint16_t digest_len

Digest length

Definition at line 531 of file dao_liquid_crypto.h.

[struct]

struct { ... } sym

Symmetric parameters. The parameters are used to calculate the size of the maximum segment size for symmetric operations.

For using following opcodes the corresponding parameters must be set:

• DAO_LC_SYM_OPCODE_FC: Flexi Crypto

  See also

  DAO_LC_SYM_FC_CTX

mod_len

uint16_t mod_len

Modulus length

Definition at line 545 of file dao_liquid_crypto.h.

exp_len

uint16_t exp_len

Exponent length

Definition at line 547 of file dao_liquid_crypto.h.

msg_len

uint16_t msg_len

Message length

Definition at line 549 of file dao_liquid_crypto.h.

[struct]

struct { ... } rsa

RSA asymmetric parameters. The parameters are used to calculate the size of the maximum segment size for asymmetric operations.

For using following APIs the corresponding parameters must be set:

• dao_liquid_crypto_enq_op_pkcs1v15enc()
• dao_liquid_crypto_enq_op_pkcs1v15dec()
• dao_liquid_crypto_enq_op_pkcs1v15enc_crt()
• dao_liquid_crypto_enq_op_pkcs1v15dec_crt()

cmd_qp

bool cmd_qp

Specifies whether the size calculation is for the command queue pair. If true, the size is calculated specifically for the command queue pair, ignoring the symmetric and RSA asymmetric parameters. If false, the size is calculated for the data queue pair using the symmetric and RSA asymmetric parameters provided above.
