Thank you, NorbertI'll use your approach, thank you very much CheersDavide On Thursday, November 30, 2023 at 11:06:09 PM GMT+1, Norbert Hartl <norbert@hartl.name> wrote: You can load the code and I think PBKDF2 does not rely on the troubling code. But when you do this you will see that it is way too slow. The number of iterations for modern crypto environment makes a single password action many seconds to complete. I use the https://github.com/PierceNg/OpenSSL-Pharo library where Iâve added two methods pbkdf2: password passwordLength: passlen salt: salt saltLength: saltlen iterations: iterations keySize: keySize result: result hashFunction: algo ^ self ffiCall: #(void PKCS5_PBKDF2_HMAC (const char* password, int passlen, const char* salt, int saltlen, int32 iterations, EVP_MD *algo, uint32 keySize, uint8* result)) and pbkdf2Password: password salt: salt iterations: iterations keySize: keySize | result | result := ByteArray new: keySize. self pbkdf2: password passwordLength: password size salt: salt saltLength: salt size iterations: iterations keySize: keySize result: result hashFunction: LcEvpSHA256 new. ^ result maybe this helps even if it is not a load and use option. The two methods can just be added as extension methods in your own code.

After that it will be easier to see why it relies on low level code like that.    Marcus

Nobody? InputEventSensor is missing in Pharo 10.
There are also several unheard requests about InputEventSensor on Discord, see attachment.

Hi Guys, The crypto repo:
Metacello new  baseline: 'Cryptography';  repository: 'github://pharo-contributions/Cryptography';  load:'core'. is not loading due to a dependency on InputEventSensor, can you help me please?
