Your example does not show encrypted, but encoded data. In this case it is base64. Use commands like
The openssl command is a little picky about the line length. You have to reformat the text, so that all but the last line are exactly 64 characters long.

Hai Friends
We have a function called char * crypt(const char *ps, const char* key) to encrypt the password in the unix environment.. Do we have any decrypt function to decrypt it? If not then how can we verify the password through program?
Thanks in Advance

bio_f_base64
BIO_f_base64(3) OpenSSL BIO_f_base64(3)NAME
BIO_f_base64 - base64 BIO filter
SYNOPSIS
#include <openssl/bio.h>
#include <openssl/evp.h>
BIO_METHOD * BIO_f_base64(void);
DESCRIPTION
BIO_f_base64() returns the base64 BIO method. This is a filter BIO that base64 encodes any data written through it and decodes any data
read through it.
Base64 BIOs do not support BIO_gets() or BIO_puts().
BIO_flush() on a base64 BIO that is being written through is used to signal that no more data is to be encoded: this is used to flush the
final block through the BIO.
The flag BIO_FLAGS_BASE64_NO_NL can be set with BIO_set_flags() to encode the data all on one line or expect the data to be all on one
line.
NOTES
Because of the format of base64 encoding the end of the encoded block cannot always be reliably determined.
RETURN VALUES
BIO_f_base64() returns the base64 BIO method.
EXAMPLES
Base64 encode the string "Hello World
" and write the result to standard output:
BIO *bio, *b64;
char message[] = "Hello World
";
b64 = BIO_new(BIO_f_base64());
bio = BIO_new_fp(stdout, BIO_NOCLOSE);
bio = BIO_push(b64, bio);
BIO_write(bio, message, strlen(message));
BIO_flush(bio);
BIO_free_all(bio);
Read Base64 encoded data from standard input and write the decoded data to standard output:
BIO *bio, *b64, *bio_out;
char inbuf[512];
int inlen;
b64 = BIO_new(BIO_f_base64());
bio = BIO_new_fp(stdin, BIO_NOCLOSE);
bio_out = BIO_new_fp(stdout, BIO_NOCLOSE);
bio = BIO_push(b64, bio);
while((inlen = BIO_read(bio, inbuf, 512) > 0)
BIO_write(bio_out, inbuf, inlen);
BIO_free_all(bio);
BUGS
The ambiguity of EOF in base64 encoded data can cause additional data following the base64 encoded block to be misinterpreted.
There should be some way of specifying a test that the BIO can perform to reliably determine EOF (for example a MIME boundary).
