Are there ready-to-use software that can try many decryption techniques on a ciphertext, with no information?
The project Cryptool does some if not all of what you want. I have not used it extensively, but it seems quite well documented. Below from the webpage:


CrypTool 1 (CT1) was the first version of CrypTool. It was released in 1998 and allows to experiment with different cryptographic algorithms. CT1 runs under Windows and has two successors: CT2 and JCT.
CrypTool 2 (CT2) supports visual programming and execution of cascades of cryptographic procedures. CT2 contains an especially large number of cryptanalysis methods and also runs under Windows.
JCrypTool (JCT) is platform-independent and runs under Linux, Mac and Windows. One focus are post-quantum (signature) algorithms.
CrypTool-Online (CTO) was released in spring 2009. Here you can try out in a browser (on a PC or a smartphone) different algorithms.


The current version of CrypTool 1 offers numerous classic and modern cryptographic algorithms (encryption and decryption, key generation, secure passwords, authentication, secure protocols, etc.)

Visualization of several algorithms (Caesar, Enigma, RSA, Diffie-Hellman, digital signatures, AES, etc.)

Cryptanalysis of several algorithms (Vigenère, RSA, AES, etc.)

Cryptanalytical measurement methods (entropy, n-grams, autocorrelation, etc.)

Related auxiliary methods (primality tests, factorization, base64 encoding, etc.)
