Determine method to Decrypt an Encrypted string

I have an encrypted string for which I know the value of the first 200 will be after decryption. I will pay for the decryption method. To not waste my time, include the first character of the decrypted string in your bid (I know what it is) Here is the first 200 characters of the encrypted string for which I need the method to decrypt: cd0ee7c3fa920f74cbe3104ab02e5bee93a8e960956q+s7fJ608iCrikaMomVyxdPbXA4eYkjTcE0TjrzJ6jIvKsr3iu7WeG9QvnWvsQJ0BnwoDJOoF3GtbFU0qlwTd4/oosqUrXgNw4AYEW/MwJx13DB2wFHAQ5KUNHaJSrGoX+Xpjo8OhZa/rtXsywjSgADCRyLD Once again, To not waste my time, include the first character of the decrypted string in your bid (I know what the first 200 characters are already) It doesnt appear to be a md5 hash or base64 which are the only 2 Ive tried before posting this
