pkcs12 output change between release 1.0.2 and 1.1.1

Hi all, The output of pkcs12 command differs between release 1.0.2 and 1.1.1. The command used is   openssl pkcs12 -passin pass: -nokeys -in signedcert.bin In the bag attributes, if the subject (and probably the issuer) contains bytes outside ASCII range, I get a different result and

Useable digest algorithms with signature

Dear All, Which digest algorithms can be used for signature with a RSA key ? sha and ripemd160 work well, but - whirlpool that works in 1.0.2o, doesn't anymore (1.1.1j) - the same applies to blake, shake Error setting context 6116:error:0408C09D:rsa routines:check_padding_md:invalid

Cheking public or private key

Dear All, Is there a way to check if a EVP_PKEY is a public or private key ? In the case of use of EVP_Sign or EVP_DigestSign functions, an application leads to crash with SIGSEGV if an incorrect key is given when finalizing process. Thanks in advance for your answers. Kind regards,

Hello, Can anybody tell me what is a possible cause of error status 20087002 : 'BIO routines:BIO_lookup:system lib' This happens only once on Debian 9 standard OpenSSL package (1.1.0l-1~deb9u1) Thank you in advance. Kind regards, Patrice.

Hello to all, Documentation does not provide input/output buffers requirements for encryption/decryption, so is it safe to submit the same buffer (ie, input=output) for these operations ? If not, what is the minimum distance 'd' required (input = output+d) ? This is to be used in small memory

Hello OpenSSL-users In the purpose of signing pdf files, I've found a difference of behaviour that I can't explain between two ways of computing signatures. The first one leads to an error in the way that Adobe says that the file was modified after signing, the second does not. First Method:

Re: Does OpenSSL supports the HTTP POST request?

Hi Yogesh Of course, yes ! SSL is completly independant of HTTP protocol. HTTP GET and POST methods differ in the way of passing parameters. On GET, parameter are passed in the URI as URI?param=valueparam=value...param=value On POST, parameters are passed in the same format
