Encryption and Decryption (as/symmetric)

Dear all, I am terribly sorry for keep spamming you with these questions. I am too fresh and too new to OpenSSL cryptography, and wishing desperately for some documents (I have looked at the SSLeay Documentation) or some information on this useful technology. I really appreciate

Padding?

Dear all, Sorry to bother you all. I am doing symmetric encryption and decryption. For encryption, I am using Java class libraries from IAIK. For decryption, I wish to use OpenSSL cryptography library. I am using Blowfish algorithm. For encryption, using CBC mode and PKC

Padding for symmetric algorithm

using OpenSSL C++ cryptography library. At encryption, I am using blowfish, CBC mode, and PKCS5 padding. Does OpenSSL cryptography library support PKCS standard padding, so that IV is not needed (please correct me if I am wrong about this statement). And, I have a char * of

Padding?

Dear all, Sorry to bother. Does symmetric algorithm provided by OpenSSL cryptography library support padding? Like PKCS5 Padding for Blowfish encryption and decryption (for IV). Thanks. Best regards, Jordan Cheun Ngen, Chong

Confused with the cryptography library.

Dear all, I am using Openssl 0.9.6 cryptograhy library. According to http://www.openssl.org/docs/crypto/EVP_EncryptInit.html there is a method EVP_CIPHER_CTX_set_padding under However I tried to find it, I couldn't find it. Is it because this is the incorrect version, or there is other reasons?

Problems with BIO_s_mem and BIO_s_file

Dear all, I have an encrypted char *, to be decrypted using the private key read from the PKCS12 protection file (which is done!!). Now the problem lies into the BIO_s_mem and BIO_s_file (the encrypted char * is Base64 encoded) I have run the two tests: 1. Store the char * into a file called "te

Encrypt and decrypt a big char array

Dear all, Sorry to bother you. I wish to encrypt a big chunk of char array (like 3000bytes) using a symmetric key (for example Blowfish 16 bytes)... However I am not sure how to do that... Could you please help me out?? I really need your expertise for this issue. Thank you very much. Wish you

Decrypt a big array of data

Dear all, Sorry to send the similar email again. I am quite frustrated here. I wish to decode a big chunk of data array with Blowfish (key size 16 bytes), ECB mode, and 1024 bytes block by block, like the following picture |--| |Big chunk of data | |--

Lost data at the buffer during symmetric block encryption

Dear All, I am sorry to bother you...I need your help... Have you faced such problem - loose some data at the end of a buffer... The code is like this I want to encrypt a file 1024 blocks by 1024 blocks and at the final block which is not 1024 blocks will do the final management like follows:
