I need to encode this

"f08b3616d575acffc9c9493a888eb4f915a6830f94101363ba01fc7c42011789"

to this

"8Is2FtV1rP/JyUk6iI60+RWmgw+UEBNjugH8fEIBF4k="

using dart and base64 encode. I used this tool base64 encode

If it helps I manage to do it on Python using this oneliner

I'm trying code a openssl HMAC SHA512 encryption but i compare my result with some online pages such HMAC-SHA256 Online Generator Tool and the result is not the same I can not figure out what i'm doing wrong, its my first time coding c++ with openssl encryption.

this is my code until now:

My hashes are different with standard sha256

How can I hash each list number to sha256 with hashlib in python?

you can see my result and other online converter results:

Im super new to encryption and so I tried to recreate a simple ECB AES-128 encryption as displayed with this online tool: https://www.devglan.com/online-tools/aes-encryption-decryption

However, when trying to encrypt the plaintext:

"parameter1=1&parameter2=2&par3=3"

using the key:

"1234567890123456"

im getting different results from the digest R implementation and the abovementioned site. Namely R gives me the hex result:

"00 63 2a 41 0a 39 0a ab b7 b9 80 b8 f1 4b 07 d9 a7 20 94 d6 b0 5b 57 17 67 68 36 a2 70 ca a2 8f"

while the online tool gives me:

"00 63 2A 41 0A 39 0A AB B7 B9 80 B8 F1 4B 07 D9 1B 09 5D 83 76 9F 6B 47 7E 51 FA D9 99 56 CE 2C B7 5A 26 54 C9 F3 6F EC 36 EF B5 D6 D2 1D 2C 0B"

Whats interesting is that the first 16 bytes are identical, but afterwards it differs.

Here is the code:

I'm searching for a python library that is capable if decrypting and encrypting RSA (RSA_PKCS1_PADDING to be precise) with a public key. I've aleready tried pycryptodome, cryptography and rsa and all of them cannot decrypt using public key. I have searched through hundreds of posts, and all answers are useless, so to filter them:

1. I am not confusing a public key with a private key
2. Public decryption is possible (I was able to do it here)
3. There is no other way around. I literally need to send public encrypted messages to the server, and recieve private encrypted messages and decrypt them with the public key

Ideally it should be something like nodejs's crypto.publicDecrypt() and crypto.publicEncrypt(). Please help me to find even if not a library, but just a function that is capable of doing it. I looked through the hundreds of posts and I'm feel like I'm going insane. Thank you.

I'm trying to decrypt a string using SubtleCrypto that was pre-generated.

Instead of getting decrypted text I'm getting the error: Failed to execute 'decrypt' on 'SubtleCrypto': parameter 2 is not of type 'CryptoKey'.

I am computing HASH value of each row in a table (for diffing purpose), after implementing the algorithm I am testing the results. Results are consistent and algorithm somewhat seems to work, but testing it step by step I found a strange result.

The script:

I used this link to test decrypting AES CBC.

Here my parameters:

This work. Then I implement with C#. My code:
