asymmetric algorithm library support in S32K118

zzzzz_ — Tue, 05 Aug 2025 07:50:13 GMT

hello,

For using S32K118 with CSEc part, may i know if NXP provide any library for asymmetric security algorithm, (mainly needed ed25519ph)

if yes from where can i get a quick integrate and perform smoke test and performance check.

if no is there any 3rd party library for S32K118 suggested.

thanks!

Hi@zzzzz

The CSEc (Cryptographic Services Engine - compressed) module in NXP's S32K1 series MCU does not support any asymmetric encryption algorithms, including RSA, ECC, Ed25519, etc.

1. There are many lightweight C libraries available online that implement Ed25519ph, Since we haven't tested this, we can't recommend it to you.

2. If performance or security requirements are high, consider connecting an external security chip that supports asymmetric encryption (such as the NXP A71CH or ATECC608A) via the SPI/I2C interface.
