Your first two steps, de-base64 and RSA-OAEP decrypt the working key, are now correct except a typo -aeop should be -oaep.. Data decryption didn't quite work because as Tom Leek says in the linked item (but I missed the first time) XMLenc block cipher does NOT use PKCS7 padding as OpenSSL does. RSA_eay_public_encrypt() then calls function RSA_padding_add_PKCS1_OAEP() implemented in rsa_oaep.c This uses SHA1 which seems to be currently the only option implemented in OpenSSL but I believe it should be possible to slightly modify code in rsa_oaep.c file to achieve what you need.

Aug 16,  · Re: RSA OAEP with sha Hi Martin, In OpenSSL implementation of OAEP, MGF1 is hardcoded with SHA-1 (look at. the end of the file rsa_oaep.c). Moreover, the function. RSA_padding_add_PKCS1_OAEP is using explicitly SHA-1 as the unique. possible hash. The encoding octet string is the base64 decoding of the content of an optional OAEPparams child element. If no OAEPparams child is provided, a null string is used. Schema Definition: An example of an RSA-OAEP element is: 9lWu3Q== If you want to use OpenSSL to decode RSA-OAEP padded data, however, the OAEPparams option cannot be proenhance-faq.com: Roger. You can generate a random bit key for AES and encrypt that key with a bit RSA public key. Then anyone which access to the private key can extract the symmetric key and decode the message with AES. The full standard for RSA is called PKCS #1. Furthermore, DES and AES are block ciphers. RSA_eay_public_encrypt() then calls function RSA_padding_add_PKCS1_OAEP() implemented in rsa_oaep.c This uses SHA1 which seems to be currently the only option implemented in OpenSSL but I believe it should be possible to slightly modify code in rsa_oaep.c file to achieve what you need. -pkeyopt rsa_oaep_md:name or rsa_mgf1_md:name where name is a hash as in your Q on PSS. bernd-edlinger added a commit to bernd-edlinger/openssl that referenced this issue Feb 28, Fix memory overrun in rsa padding check functions Fixes openssl# and openssl# I want to use RSAES-OAEP algorithm. with SHA as hash function and MGF1 as mask generation function. I want do this using openssl. I found a function RSA_public_encrypt() with this function we can specify the padding. One of the padding option available was. RSA_PKCS1_OAEP_PADDING EME-OAEP as defined in PKCS #1 v with SHA-1, MGF1.
