Is there any way to access the OpenSSL PKCS5_PBKDF2_HMAC_SHA1()

Hi,
I want to use openssl to encrypt and decrypt files using asymmetric

I tried to do symmetric encryption with enc, works fine. Example:
openssl enc -e -aes128 -pass file:/path/to/passkey
What command is used for asymmetric? What kind of keys do you recommend

Yes, this function internally looks like PBKDF2 and has similar use

PBKDF2 from PKCS#5 realized by EVP_BytesToKey() in OpenSSL.
I don't remember exactly but there was some incompatibility

Thank you Girish, I understand now. The combination: encrypt with
public key - decrypt with private works.
What we are trying to do is to place an encrypted file on our ftp server
for a specific user. The ftp server is behind a firewall, and the user
can access and see only its account, and they

I am trying to do the following:

- encrypt a file and place on an ftp server
- the client will pick up the file and decrypt it using the PUBLIC key
Here is what I did to create the certificate

Depends on what you mean by "file enc
Does OpenSSL have a stream interface for file encryption? For example, is
there a stream-based method of encrypting a file in pieces rather than
loading an entire file into memory?

Hi Everybody,
we are trying to encrypt a file using the openssl command.
openssl enc -ciphername [-in filename] [-out filename] [-pass arg] [-e] [-d] [-a] [-A] [-k password] [-kfile filename] [-K key] [-iv IV] [-p] [-P] [-bufsize number] [-debugopenssl enc -ciphername [-in filename]
Hi,
Does any one know any file encryption application, based on openssl or not,
that uses hybrid cryptosystems (like PGP) with digital certificates support.
Thanks

I want to use a file/disk encryption tool on Win95/98, like an EFS on Win2000.
The automatic encryption/decryption feature of EFS is very attractive for me.
Please tell me some good tools.
Thank you.
