Filling a RSA *key variable with a public key from a Hex string

Hi all, I am having some trouble finding a library/API function which makes it possible to specify the public (or private) encryption key as a Hex string. PEM_read_bio_RSA_PUBKEY will not do it for me, as I do not have a PEM-file. My alternative is to insert the data directly into the rsa_st

RSA OAEP encrypt with a label

Hi all, How is it possible to RSA OAEP encrypt using a label in addition to the public encryption key and the message width libcrypto? The operation would be that of RSAES-OAEP-ENCRYPT((n, e), M, L), as specified in the RSA Cryptography Standard version 2.1. I do not find any possibility to add

Re: RSA OAEP encrypt with a label

Thank you Martin. I have tried using the function, however using the code I have pasted below I get the error Error = oaep decoding error when trying to unpadd to retrieve the original data. For simplicity the code I have added here does not encrypt/decrypt, but only attempts to pad and unpadd.
